[pt] Esta tese propõe um método meshfree adaptativo de advecção para problemas de fluxo bifásico de fluidos incompressíveis e imiscíveis em meios porosos heterogêneos tridimensionais. Este método se baseia principalmente na combinação do método Semi-Lagrangeano adaptativo com interpolação local meshfree usando splines poliharmônicas como funções de base radial. O método proposto é uma melhoria e uma extensão do método adaptativo meshfree AMMoC proposto por Iske e Kaser (2005) para modelagem 2D de reservatórios de petróleo. Inicialmente este trabalho propõe um modelo em duas dimensões, contribuindo com uma melhoria significativa no cálculo do Laplaciano, utilizando os métodos meshfree de Hermite e Kansa. Depois, o método é ampliado para três dimensões (3D) e para um meio poroso heterogêneo. O método proposto é testado com o problema de five spot e os resultados são comparados com os obtidos por sistemas bem conhecidos na indústria de petróleo.

[en] This thesis proposes an adaptive meshfree advection method for two-phase flow problems of incompressible and immiscible fluids through three-dimensional heterogeneous porous media. This method is based mainly on a combination of adaptive semi-Lagrangian method with local meshfree interpolation using polyharmonic splines as radial basis functions. The proposed method is an improvement and extension of the adaptive meshfree advection scheme AMMoC proposed by Iske and Kaser (2005) for 2D oil reservoir modeling. Initially this work proposes a model in two dimensions, contributing to a significant improvement in the calculation of the Laplacian, using the meshfree methods of Hermite and Kansa. Then, the method is extended to three dimensions (3D) and a heterogeneous porous medium. The proposed method is tested with the five spot problem and the results are compared with those obtained by well-known systems in the oil industry.

▼ We study stockpiling problems under uncertain economic and physical factors, and investigate the valuation and optimisation of storage systems where the availability and spot price of the underlying are both subject to stochasticity. Following a Real Options valuation approach, we ﬁrst study ﬁnancial derivatives linked to Asian options. A comprehensive set of boundary conditions is compiled, and an alternative (and novel) similarity reduction for ﬁxed-strike Asian options is derived. Hybrid semi-Lagrangian methods for numerically solving the related partial diﬀerential equations (PDEs) are implemented, and we assess the accuracy of the valuations thus obtained with respect to results from classical ﬁnite-diﬀerence valuation methods and with respect to high precision calculations for valuing Asian options with spectral expansion theory techniques. Next we derive a PDE model for valuing the storage of electricity from a wind farm, with an attached back-up battery, that operates by trading electricity in a volatile market in order to meet a contracted ﬁxed rate of energy generation; this system comprises two diﬀusive-type (stochastic) variables, namely the energy production and the electricity spot price, and two time-like (deterministic) variables, speciﬁcally the battery state and time itself. An eﬃcient and novel semi-Lagrangian alternating-direction implicit (SLADI) methodology for numerically solving advection-diﬀusion problems is developed: here a semi-Lagrangian approach for hyperbolic problems of advection is combined with an alternating-direction implicit method for parabolic problems involving diﬀusion. Eﬃciency is obtained by solving (just) tridiagonal systems of equations at every time step. The results are compared to more standard semi-Lagrangian Crank-Nicolson (SLCN) and semi-Lagrangian fully implicit (SLFI) methods. Once he have established our PDE model for a storage-upgraded wind farm, a system that depends heavily on the highly stochastic nature of wind and the volatile market where electricity is sold, we derive a Hamilton-Jacobi-Bellman (HJB) equation for optimally controlling charging and discharging rates of the battery in time, and we assess a series of operation regimes. The solution of the related PDE models is approached numerically using our SLADI methodology to eﬃciently treat this mixed advection and diﬀusion problem in four dimensions. Extensive numerical experimentation conﬁrms our SLADI methodology to be robust and yields highly accurate solutions and eﬃcient computations, we also explore eﬀects from correlation between stochastic electricity generation and random prices of electricity as well as eﬀects from a seasonal electricity spot price. Ultimately, the objective of approximating optimal storage policies for a system under uncertain economic and physical factors is accomplished. Finally we examine the steady-state solution of a stochastic storage problem under uncertain electricity market prices and ﬁxed demand. We use a HJB formulation for optimally controlling charging and… Advisors/Committee Members: JOHNSON, PAUL PV, Duck, Peter, Johnson, Paul.

▼ This study considers higher-order spatial and temporal methods for a conservative semi-implicit semi-Lagrangian (SISL) discretization of the atmospheric dynamical equations. With regard to spatial accuracy, new subgrid approximations are tested in the Conservative Cascade Scheme (CCS) SL transport algorithm. When developed, the CCS used the monotonic Piecewise Parabolic Method (PPM) to reconstruct cell variation. This study adapts four new non-polynomial methods to the CCS context: the Piecewise Hyperbolic Method (PHM), Piecewise Double Hyperbolic Method (PDHM), Piecewise Double Logarighmic Method (PDLM), and Piecewise Rational Method (PRM) for comparison against PPM. Additionally, an adaptive hybrid approximation scheme, PPM-Hybrid (PPM-H), is constructed using monotonic PPM for smooth data and local extrema and using PHM for steep jumps where PPM typically suffers large accuracy degradation. Smooth and non-smooth data profiles are transported in 1-D, 2-D Cartesian, and 2-D spherical frameworks under uniform advection, solid body rotation, and deformational flow. Accuracy is compared in the L₁ error measure. PHM performed up to five times better than PPM for smooth functions but up to two times worse for non-smooth functions. PRM performed very similarly to PPM for non-smooth functions but the order of convergence was worse than PPM for smooth data. PDHM performed the worst of all of the non-polynomial methods for almost every test case. PPM-H outperformed both PPM and all of the new methods for all test cases in all geometries offering a robust advantage in the CCS scheme. Additionally, the CCS and new subgrid approximations were used to perform conservative grid-to-grid interpolation between two spherical grids in latitude / longitude coordinates. The methods were tested by prescribing an analytical sine wave function which was integrated over grid cells at T-42 resolution (approximately 2.8ˆ{o} imes2.8ˆ{o}) and at 1ˆ{o} resolution. Then, the 1ˆ{o} data is interpolated to the T-42 grid to compare against the analytical formulation. Three test data sets were created with increasing sharpness in the sine wave profiles by spanning 1, 3, and 9 wavelengths across the domain. It was found that in all test cases, PDHM performed the best in the interpolation scheme, better than PPM. Regarding temporal accuracy, a linear, SISL 2-D dynamical model is given harmonic input for the dependent variables to extract a Von-Neumann analysis of the SISL numerical modification of the solution. The Boussinesq approximation is relaxed, and spatial error is removed in order to isolate only temporal accuracy. A hydrostatic switch is employed to invoke and remove non-hydrostatic dynamics. Trajectory uncentering (typically used to suppress spurious orographic SISL resonance) is included by altering the coefficients of the forcing terms of the linear equations. It was found that with regard to Internal Gravity Wave (IGW) motion, the first-, second-, and third-order Adams-Moulton (AM) schemes performed with… Advisors/Committee Members: Dr. Fredrick H. M.

▼ This dissertations focuses on solving the advection problem with the motivation of simulating transport in porous media. A quadrature based Eulerian-Lagrangian scheme is developed to solve the nonlinear advection problem in multiple spatial dimensions. The schemes combines the ideas of Lagrangian traceline methods with high order WENO reconstructions to compute the mass that flows into a given cell over a time step. These schemes are important since they have a relaxed CFL constraint, and can be run in parallel. In this thesis we provide two improvements to Eulerian-Lagrangian schemes. To do this an integration based WENO (IWENO) interpolation technique is derived by reconstructing the primitive function and differentiating. This technique gives a high order reconstruction of the mass at an arbitrary point. This WENO scheme is used to solve the linear advection problem. A scheme is derived by backwards tracing of quadrature points located on mesh elements. The mass at these tracepoints is used to compute the mass in the trace region, without resolving its boundary. This process defines a high order quadrature Eulerian-Lagrangian WENO (QEL-WENO) scheme that solves the multi-dimensional problem without the need for a spatial splitting technique. The second improvement is for solving the nonlinear advection problem using an approximate velocity field. The velocity field is used to transport mass in the manner of a standard Eulerian-Lagrangian scheme. Then a flux correction is applied to compute the flow across the tracelines. The contribution is to use a variation of the IWENO technique to reduce the stencil size of this computation. Numerical results are presented demonstrating the capabilities of the scheme. An application to two-phase flow in porous media is provided.

▼ Prediction of ductile fracture, which is a prevalent failure mode in most engineering structures, is vital to numerous industries. Despite significant advancements in fracture mechanics, ductile fracture modeling has remained a challenging task and a continuing area of research. The peridynamic theory has attracted broad interest in recent years, for its innovative approach for simulating material damage. While peridynamics has been largely utilized to simulate cracking events in brittle materials, its ability in predicting ductile failure remains mostly untested. In this dissertation, a rigorous investigation into the capabilities of peridynamics in simulating ductile fracture in metallic alloys is undertaken. The third Sandia Fracture Challenge, as a true blind prediction challenge, is employed in this examination. In this challenge, the state of the art of the peridynamic modeling of ductile fracture is implemented to predict deformations and failure of an additively manufactured metal, with a complex geometry, under the dynamic tensile experiments performed by Sandia National Laboratories. Following the participation in the challenge, while our modeling approach led to qualitatively good blind predictions and a correctly predicted crack path, it underpredicted the load-carrying capacity of the structure and simulated an early fracture. Our post-experiment analysis identifies the main sources of discrepancy between the blind simulations and experiments to be (1) material instabilities associated with the finite deformation peridynamic model and (2) unreliability of a Lagrangian peridynamic framework in solving problems involving extremely large deformation and extensive damage. To address the aforementioned issues, a novel bond-associated, semi-Lagrangian, constitutive correspondence, peridynamic framework is proposed, in which peridynamic material point interactions depend only on their current properties (e.g. position and stress values) in the deformed configuration, and a rate-based approach is utilized to advance the state of material. A nonlocal version of the velocity gradient is presented to determine the Cauchy stress rate, using local constitutive theories, as an intermediate quantity in computing peridynamic bond forces. A novel bond-associated, correspondence damage modeling is introduced by using the bond-associated internal properties, e.g. stress and strain values, to incorporate classical failure criteria within the peridynamic framework. The new theory is employed to revisit the Sandia Fracture Challenge problem. Our results indicate that the new approach significantly improves the peridynamic predictions of large deformation and ductile fracture Advisors/Committee Members: Foster, John T., Ph. D.

▼ We present algorithms and software for parameter estimation for forward and inverse tumor growth problems and diffeomorphic image registration. Our methods target the following scenarios: automatic image registration of healthy images to tumor bearing medical images and parameter estimation/calibration of tumor models. This thesis focuses on robust and scalable algorithms for these problems. Although the proposed framework applies to many problems in oncology, we focus on primary brain tumors and in particular low and high-grade gliomas. For the tumor model, the main quantity of interest is the extent of tumor infiltration into the brain, beyond what is visible in imaging. The inverse tumor problem assumes that we have patient images at two (or more) well-separated times so that we can observe the tumor growth. Also, the inverse problem requires that the two images are segmented. But in a clinical setting such information is usually not available. In a typical case, we just have multimodal magnetic resonance images with no segmentation. We address this lack of information by solving a coupled inverse registration and tumor problem. The role of image registration is to find a plausible mapping between the patient's tumor-bearing image and a normal brain (atlas), with known segmentation. Solving this coupled inverse problem has a prohibitive computational cost, especially in 3D. To address this challenge we have developed novel schemes, scaled up to 200K cores. Our main contributions is the design and implementation of fast solvers for these problems. We also study the performance for the tumor parameter estimation and registration solvers and their algorithmic scalability. In particular, we introduce the following novel algorithms: An adjoint formulation for tumor-growth problems with/without mass-effect; The first parallel 3D Newton-Krylov method for large diffeomorphic image registration; A novel parallel semi-Lagrangian algorithm for solving advection equations in image registration and its parallel implementation on shared and distributed memory architectures; and Accelerated FFT (AccFFT), an open-source parallel FFT library for CPU and GPUs scaled up to 131,000 cores with optimized kernels for computing spectral operators. The scientific outcomes of this thesis, has appeared in the proceedings of three ACM/IEEE SCxy conferences (two best student paper finalist, and one ACM SRC gold medal), two journal papers, two papers in review, four papers in preparation (coupling, mass effect, segmentation, and multi-species tumor model), and seven conference presentations.

▼ The study of projectile penetration has a long history with a great military research interest for various applications such as projectile’s design to maximize depth of penetration into different materials, or penetration depth prediction for munitions removal for military training sites. The nature of the problem involves complex physics and mechanics, leading to extremely large deformations, high velocity penetration, and highly fragmented configurations, which in turn posts immense challenges in computational simulations. The aims of this study is to develop computational tools, addressing challenges at micro- and macro-scales, to simulate and study mechanisms of projectile penetration into soils. Within a hierarchical multiscale framework, a microscale model accounting micro defeats and their evolution can be simulated in detail in order to develop physically based constitutive models for geomaterials. However, simulating an excessive amount of defeats and how they propagate, branch, and nuclear, remains a big challenge in computation. The phase-field variational approaches have gained considerable amount of interest to address challenges abovementioned. However, phase-field becomes a computationally expensive method when narrow-width crack with a small value for length-scale parameter is required, which demands an extremely fine mesh close to the crack initiation location and on its propagation path. Moreover, Galerkin methods require quadrature rule for numerical integration which leads to either integration inaccuracy and instability or excessively high computational cost. To overcome domain integration issues and mesh-size dependency of the phase-field approach, two new methods are introduced within the Reproducing Kernel (RK) collocation method. A high-order gradient reproducing kernel collocation method (HGRKCM) is introduced for solving higher order phase-field formulation, such as the fourth-order formulation which increases the regularity of the phase-field solution. The method provides stable and accurate solutions by solving the determined system of equations and gradient derivatives of RK shape functions, which boost the computational efficiency compared to regular RK collocation methods. Besides, a Harmonic RK (HRK) method is introduced to address the mesh-decency of the phase-field problem. The method provides exact approximation for the phase-field solution up to machine limit with considerably coarser nodal distant size compared to other methods. Harmonic-enriched RK in the HGRKCM framework provide a robust method for solving the phase-field problem in term of both accuracy and efficiency. To simulate the penetration process at the macroscale, a two-field (u - p) formulation based on the Biot theory has been developed and implemented under the semi-Lagrangian RK framework, where displacement and pressure fields are independently approximated by the semi-Lagrangian RK shape functions. A Drucker-Prager type constitutive model including a one-parameter damage model is employed to simulate the… Advisors/Committee Members: Chi, Sheng-Wei (advisor), Foster, Craig (committee member), Ozevin, Didem (committee member), Karpov, Eduard (committee member), Shabana, Ahmed (committee member), Chi, Sheng-Wei (chair).

Os escoamentos altamente convectivos representam um desafio na simulação pelo método de elementos finitos. Com a solução de elementos finitos de Galerkin para escoamentos incompressíveis, a matriz associada ao termo convectivo é não simétrica, e portanto, a propiedade de aproximação ótima é perdida. Na prática as soluções apresentam oscilações espúrias. Muitos métodos foram desenvolvidos com o fim de resolver esse problema. Neste trabalho apresentamos um método semi- Lagrangeano, o qual é implicitamente um método do tipo upwind, que portanto resolve o problema anterior, e comparamos o desempenho do método na solução das equações de convecção-difusão e Navier-Stokes incompressível com o Streamline Upwind Petrov Galerkin (SUPG), um método estabilizador de reconhecido desempenho. No SUPG, as funções de forma e de teste são tomadas em espaços diferentes, criando um efeito tal que as oscilações espúrias são drasticamente atenuadas. O método semi-Lagrangeano é um método de fator de integração, no qual o fator é um operador de convecção que se desloca para um sistema de coordenadas móveis no fluido, mas restabelece o sistema de coordenadas Lagrangeanas depois de cada passo de tempo. Isto prevê estabilidade e a possibilidade de utilizar passos de tempo maiores.Existem muitos trabalhos na literatura analisando métodos estabilizadores, mas não assim com o método semi-Lagrangeano, o que representa a contribuição principal deste trabalho: reconhecer as virtudes e as fraquezas do método semi-Lagrangeano em escoamentos dominados pelo fenômeno de convecção.

Convection dominated flows represent a challenge for finite element method simulation. Many methods have been developed to address this problem. In this work we compare the performance of two methods in the solution of the convectiondiffusion and Navier-Stokes equations on environmental flow problems: the Streamline Upwind Petrov Galerkin (SUPG) and the semi-Lagrangian method. In Galerkin finite element methods for fluid flows, the matrix associated with the convective term is non-symmetric, and as a result, the best approximation property is lost. In practice, solutions are often corrupted by espurious oscillations. In this work, we present a semi- Lagrangian method, which is implicitly an upwind method, therefore solving the spurious oscillations problem, and a comparison between this semi-Lagrangian method and the Streamline Upwind Petrov Galerkin (SUPG), an stabilizing method of recognized performance. The SUPG method takes the interpolation and the weighting functions in different spaces, creating an effect so that the spurious oscillations are drastically attenuated. The semi-Lagrangean method is a integration factor method, in which the factor is an operator that shifts to a coordinate system that moves with the fluid, but it resets the Lagrangian coordinate system after each time step. This provides stability and the possibility to take bigger time steps. There are many works in the literature analyzing stabilized methods, but they do not analyze the semi-Lagrangian…

Les instabilités de type Weibel naissent si la distribution des vitesses du plasma présente une anisotropie. Elles entraînent la génération d’un champ magnétique dû à la formation de filaments de courant ainsi qu’une activité électrostatique importante. Ces phénomènes de base apparaissent dans de nombreuses situations, naturelles (vent solaire, jets relativistes) ou expérimentales (interaction laser-plasma) : les plasmas dans lesquels ils naissent peuvent être relativistes ou non, magnétisés ou non, collisionnels ou non, ce qui pose la question du choix du modèle à utiliser pour les décrire. La théorie cinétique est le cadre le plus complexe dans lequel nous travaillerons. De par sa complexité, il est intéressant de développer des modèles réduits. Un premier travail mené au cours de cette thèse est l’utilisation d’un modèle fluide incluant la dynamique du tenseur de pression pour modéliser la phase linéaire des instabilités de type Weibel. On discute le rôle essentiel joué par les composantes hors diagonale du tenseur dans la génération du champ magnétique, puis la capacité du modèle à reproduire quantitativement ou qualitativement les résultats cinétiques en introduisant la notion de limite hydrodynamique. La seconde partie de la thèse est ciblée sur le développement du code semi-lagrangien relativiste VLEM utilisant une méthode de décomposition de domaine : on présente les principales méthodes mathématiques utilisées dans le code, puis on aborde la problématique de la conservation de la charge à laquelle on apporte une réponse reposant sur une adaptation de la méthode d’Esirkepov. Le code est enfin validé grâce à plusieurs simulations d’instabilités de type Weibel

Weibel-type instabilities occurs when the velocity distribution function of the charged particles displays a pronounced anisotropy. A long-lasting magnetic field is generated due to the formation of current filaments, and it is accompanied by an important electrostatic activity. These ``basic’’ phenomena have been greatly investigated because of their involvement in many physical problems, natural (solar wind, relativistic jets) or experimental (laser-plasma interaction) : they occurs in plasmas which can be collisional or not, magnetised or not, relativistic or not. One needs to choose a suitable model for their description. The kinetic theory is the most complete and somewhat complex theoretical framework which we will consider. Due to its complexity, it may be interesting to develop reduced models. The first work realised during this thesis is the utilisation of a non-relativistic fluid description, including the dynamics of the pressure tensor, in order to model the linear Weibel-type instabilities. We put in evidence the effect of the non-diagonal components of the tensor on the magnetic field generation. We discuss the ability of the model to reproduce quantitatively or qualitatively the kinetic results by introducing the hydrodynamics limit. The second part of this thesis work is dedicated to the development of the relativistic semi-lagrangian…

Ce manuscrit de thèse traite de l'analyse asymptotique de problèmes paraboliques possédant des termes raides. Dans un premier temps, on fait l'analyse asymptotique d'un système parabolique possédant des termes de transport raide. Une analyse à deux échelles, basée sur des résultats de théorie ergodique, nous permet de dériver un système limite effectif. Ce système effectif se trouve être, de nouveau, un système parabolique dont le champ de diffusion peut être explicité par une moyenne du champ de diffusion initial le long d'un groupe d'opérateurs unitaires. L'introduction d'un correcteur nous permet d'obtenir un résultat de convergence forte, avec un ordre de convergence, pour des données initiales non nécessairement bien préparées. On propose dans un second temps une méthode numérique permettant de calculer le champ de diffusion effectif. Celle-ci est basée sur la combinaison d'un schéma Runge-Kutta et d'un schéma de type semi-Lagrangien. L'ordre de convergence obtenu théoriquement est mis en évidence de manière numérique. On propose une méthode numérique basée sur un splitting d'opérateur pour la résolution du système parabolique avec termes de transport raide. Enfin, on effectue l'analyse asymptotique d'un système parabolique fortement anisotrope. Sous de bonnes hypothèses de régularité, un système variationnel effectif est proposé et l'introduction d'un correcteur adapté permet d'obtenir un résultat de convergence forte avec un ordre de convergence. Les arguments utilisés relèvent une nouvelle fois de l'analyse à deux échelles et de la théorie ergodique.

This manuscript is devoted to the asymptotic analysis of parabolic equations with stiff terms. First, we perform the asymptotic analysis of a parabolic equation with stiff transport terms. An effective limit model is obtained by a two-scale analysis based on ergodic theory results. This effective system is again a parabolic system whose diffusion field is an average of the initial diffusion field along a group of unitary operators. The introduction of a corrector allows us to obtain a strong convergence result, with an order of convergence, for initial data not necessarily well prepared. We propose a numerical method to compute the effective diffusion field. This method is based on a Runge-Kutta scheme and a semi-Lagrangian scheme. The theoretically order of convergence is obtained numerically. We propose a numerical method based on operator splitting for the resolution of the parabolic system with stiff transport terms. Finally, we perform the asymptotic analysis of a strongly anisotropic parabolic problem. Under suitable smoothness hypotheses, an effective variational system is proposed. By using a suitable corrector, we obtain a strong convergence result and we are able to perform the error analysis. The arguments relate again to the two-scale analysis and the ergodic theory.

▼ The non-hydrostatic dynamical core ENDGame (Even Newer Dynamics for the General Atmospheric Modelling of the Environment) is extended into the thermosphere to test its feasability as a whole-atmosphere dynamical core that can simulate the large scale fluid dynamics of the whole atmosphere from the surface to the top of the thermosphere at 600km. This research may have applications in the development of a Sun-to-Earth modelling system involving the Met Office Unified Model, which will be useful for space weather forecasting and chemical climate modelling. Initial attempts to raise the top boundary of ENDGame above ∼100km give rise to instabilities. To explore the potential causes of these instabilities, a one dimensional column version of ENDGame: ENDGame1D, is developed to study the effects of vertically propagating acoustic waves in the dynamical core. A 2D ray-tracing scheme is also developed, which accounts for the numerical effects on wave propagation. It is found that ENDGame’s numerics have a tendency towards the excessive focussing of wave energy towards vertical propagation, and have poor handling of large amplitude waves, also being unable to handle shocks. A key finding is that the physical processes of vertical molecular viscosity and diffusion prevent the excessive growth of wave amplitudes in the thermosphere in ENDGame, which may be crucial to improving ENDGame’s stability as it is extended upwards. Therefore, a fully implicit-in-time implementation of vertical molecular viscosity and diffusion is developed in both ENDGame1D and the full three-dimensional version of ENDGame: ENDGame3D. A new scheme is developed to deal with the viscous and diffusive terms with the dynamics terms in a fully coupled way to avoid time-splitting errors that may arise. The combination of a small amount of off-centring of ENDGame’s semi-implicit formulation and the inclusion of vertical molecular viscosity and diffusion act to make ENDGame significantly more stable, as long as the simulation is able to remain stable up to the molecularly diffused region above an altitude of ∼130km.

Ce travail concerne l’écoulement incompressible et stationnaire autour d’un cylindre semi-infini en rotation, et ses propriétés de stabilité linéaire. L’effet de la courbure et de la rotation sur la stabilité de cet écoulement est étudié de manière systématique. Avant d’étudier la stabilité, nous calculons d’abord l’écoulement de base. A grand nombre de Reynolds, une couche limite se développe le long du cylindre, ce qui permet d’utiliser l’approximation de couche limite des équations de Navier–Stokes. Ces équations dépendent de deux paramètres de contrôle sans dimension, le nombre de Reynolds (Re) et le taux de rotation (S), et sont résolues numériquement pour obtenir les profils de vitesse et de pression pour une large gamme des paramètres de contrôle. Une couche limite initialement mince s’épaissit avec la distance axiale; ainsi, son épaisseur devient comparable et finalement plus importante que le rayon du cylindre. Au-delà d’un certain taux de rotation, les effets centrifuges conduisent `a un jet de paroi le long d’une portion du cylindre. L’extension axiale de ce jet augmente avec le taux de rotation. L’intensité du jet augmente aussi avec S. Des analyses asymptotiques de l’écoulement à grande distance axiale et à fort taux de rotation sont aussi présentées. L’analyse de stabilité linéaire du précédent écoulement est effectuée dans l’approximation locale. Après une décomposition en modes normaux, les équations des perturbations sont transformées en un problème de valeur propre `a fréquence complexe (ω). Ce problème dépend de cinq paramètres sans dimension: Re, S, la distance axiale normalisée (Z), le nombre d’onde axial (α) et le nombre d’onde azimutal (m). Les équations de stabilité sont résolues numériquement pour étudier les régions instables dans l’espace des paramètres. On observe que de faibles taux de rotation ont un effet important sur la stabilité de l’écoulement. Cette forte déstabilisation est associée à la présence d’un mode quasi-marginal pour le cylindre fixe et qui devient instable pour de petites valeurs de S. Ce phénomène est confirmé par une analyse en perturbation `a petit S. Sans rotation, l’écoulement est stable pour tout Re < 1060, et pour Z > 0.81. Mais, en présence d’une faible rotation, l’instabilité n’est plus limitée par une valeur minimale de Re ou un seuil en Z. Les courbes critiques dans le plan (Z, Re) sont calculées pour une large gamme de S et les conséquences pour la stabilité de l’écoulement discutées. Enfin, un développement asymptotique pour le nombre de Reynolds critique est obtenu, valable aux grandes valeurs de Z.

This work concerns the steady, incompressible flow around a semi-infinite, rotating cylinder and its linear-stability properties. The effect of cylinder curvature and rotation on the stability of this flow is investigated in a systematic manner. Prior to studying its stability, we first compute the basic flow. At large Reynolds numbers, a boundary layer develops along the cylinder. The governing equations are obtained using a boundary-layer approximation to…

[pt] Ao longo dos anos, a interação aço-concreto tem obtido um lugar de destaque do ponto de vista estrutural, ampliando a gama de soluções em concreto armado e aço, o que permite atender aos novos desafios arquitetônicos e às exigências que o mercado impõe. O objetivo do sistema misto é a combinação desses dois materiais, formando um único sistema estrutural em que a capacidade portante de cada elemento possa ser explorada ao máximo, tirando-se proveito da grande capacidade do concreto resistir a esforços de compressão, e de o aço, à tração. Essas características singulares de sistemas mistos aço-concreto conduzem a frequências naturais mais próximas da faixa de frequência de excitações associada às atividades humanas. Sendo assim, as considerações relacionadas ao projeto estrutural obrigam os engenheiros a fazer verificações quanto à resistência e à estabilidade de sistemas estruturais (estados limites últimos), mas os problemas relacionados ao estado limite de utilização desses sistemas devem ser analisados de forma mais cuidadosa. Embora o assunto de vibrações em lajes de edifícios induzidas por atividades humanas tem sido de continuado interesse a pesquisadores e a engenheiros ao longo dos últimos dois séculos (1828-2009), inexiste na literatura técnica, até onde o autor tem conhecimento, análise de correlações teórico-experimentais de vibrações de estruturas mistas aço-concreto sob ação de atividades humanas, na qual são consideradas a ortotropia, a interação parcial e as ligações semirrígidas. Com o objetivo de contribuir nessa direção, o presente trabalho investiga o efeito da interação aço-concreto sobre a resposta dinâmica de sistemas de pisos mistos.

[en] Over the years the steel-concrete interaction have been achieving excelent results, in terms of structural performance. This fact have enlarged the range of applications of concrete and steel structures enabling the development of efficient solutions that attend the demands claimed by the market and by increasinly daring architectures. The composite action main objective is to combine steel and concrete into single structural system where the optimum performance of the combined elements could be explored. The concrete is used to sustain compressive while the steel is better used when submitted to tension. These singular characteristics of the composite systems, on the other hand, lead to composite structural systems with natural frequencies close to the frequency associated to human induced loads. Usually the design of composite structures is focused on verifications related to ultimate limit states associated to strength and stability, but the problems related to serviceability limit states should also be carefully considered. Despite the fact that floor vibration induced by human activity has been extensively investigated in the past (1828-2009) there is still a lack of published information on theoretical-experimental correlations on the dynamic response of composite structures specially after considering effects releted to partial interaction,…

[pt] A caracterização das pressões de poros nas bacias sedimentares marinhas é fundamental dentro da etapa de planejamento dos projetos de perfuração na indústria do Petróleo. Uma vez que o desconhecimento dessas pressões coloca em risco a integridade das pessoas nas sondas de perfuração, o ambiente, além de causar grandes prejuízos para as companhias. As metodologias para a estimativa das poropressões na indústria do petróleo tiveram grande desenvolvimento a partir da década de1950. Porém, a grande maioria delas não levam em consideração caraterísticas geológicas importantes como a diagêneses das rochas, as condições de contorno para o fluxo de fluidos, e os mecanismos de dissipação das sobrepressões durante o tempo geológico. Por isso, o principal objetivo do trabalho é fortalecer os estudos convencionais de estimativa de pressão de poros incluindo uma metodologia não convencional com abordagem na modelagem de bacias. Essa metodologia permite analisar o fenômeno como um sistema dinâmico, bem como levar em consideração os mecanismos de geração e de dissipação das pressões durante a evolução geológica da Bacia. Apresenta-se a descrição dos principais mecanismos de geração de sobrepressão, a teoria que descreve o fenômeno das sobrepressões, as metodologias convencionais utilizadas na indústria do petróleo e as hipóteses da metodologia baseada na modelagem de bacias. Utilizou-se o software SEMIMT, do instituto de pesquisa da Noruega, o SINTEF, para realizar a estimativa das poropressões na Bacia de Guajira, uma região offshore do norte da Colômbia. A estimativa das pressões considerou os contornos da bacia, o modelo geológico da região, o histórico de soterramento da Bacia, bem como de modelos de compactação e os modelos de fluxo vertical e fluxo horizontal dos fluidos. O resultado da estimativa das pressões permitiu definir quatro zonas com diferente grau de sobrepressão na área em estudo, que foram comparados com uma metodologia convencional, bem com dados históricos de poços perfurados na região.

[en] Pore pressure prediction is a critical issue for well planning in the oil and gas industry. It is even more critical for offshore environments due to high risks involved in drilling operation. Blowout is the main risk regarding pore pressure since it could cause rig explosion, and oil spills to environment. Such problems can lead a successful company to a very weak position. Therefore, since the fifties, several methodologies for pore pressure prediction have been developed for the industry. Most of them just consider the mechanism of compaction as the main cause of overpressure, ignoring other factors such as rock diagenesis, boundary conditions for fluid flow, and pressure dissipation during the geologic history. That is why the main objective of this work is improving current pore pressure studies, including an alternative methodology (developed by the Norway Petroleum Research Institute - SINTEF), from a scale of basin modeling. That methodology allows analyzing the pressure phenomenon like a dynamic system,…

[pt] Tarefas de exploração de informação são reconhecidas por possuir características tais como alta complexidade, falta de conhecimento do usuário sobre o domínio da tarefa e incertezas sobre as estratégias de solução. O estado-da-arte em exploração de dados inclui uma variedade de modelos e ferramentas baseadas em diferentes paradigmas de interação, como por exemplo, busca por palavras-chave, busca facetada e orientação-a-conjuntos. Não obstante os muitos avanços das últimas décadas, a falta de uma abordagem formal do processo de exploração, juntamente com a falta de uma adoção mais pragmática do princípio de separação-de-responsabilidades no design dessas ferramentas são a causa de muitas limitações. Dentre as limitações, essa tese aborda a falta de expressividade, caracterizada por restrições na gama de estratégias de solução possíveis, e dificuldades de análise e comparação entre as ferramentas propostas. A partir desta observação, o presente trabalho propõe um modelo formal de ações e processos de exploração, uma nova abordagem para o projeto de ferramentas de exploração e uma ferramenta que generaliza o estado-da-arte em exploração de informação. As avaliações do modelo, realizadas por meio de estudos de caso, análises e comparações o estado-da-arte, corroboram a utilidade da abordagem.

[en] Information exploration processes are usually recognized by their inherent complexity, lack of knowledge and uncertainty, concerning both the domain and the solution strategies. Even though there has been much work on the development of computational systems supporting exploration tasks, such as faceted search and set-oriented interfaces, the lack of a formal understanding of the exploration process and the absence of a proper separation of concerns approach in the design phase is the cause of many expressivity issues and serious limitations. This work proposes a novel design approach of exploration tools based on a formal framework for representing exploration actions and processes. Moreover, we present a new exploration system that generalizes the majority of the state-of-the art exploration tools. The evaluation of the proposed framework is guided by case studies and comparisons with state-of-the-art tools. The results show the relevance of our approach both for the design of new exploration tools with higher expressiveness, and formal assessments and comparisons between different tools.

▼ During the work of this research project we were interested in mathematical techniques that give us an insight to the following questions: How do we understand the trading decisions made by a manager of a hedge fund and what influences these decisions? In what way does an illiquid market affect these decisions and the performance of the fund? And how does the payment scheme affect the investor's decisions? Based on existing work on hedge fund management, we start with a fund that can be modelled with one risky investment and one riskless investment. Next, subject to the hedge fund special reward scheme we maximise the expected utility of wealth of the manager, by controlling the percentage invested in the risky investment, namely the portfolio. We use stochastic control techniques to derive a partial differential equation (PDE) and numerically obtain its corresponding viscosity solution, which provides a weak notion of solutions to these PDEs. This is then taken to a liquidity constrained scenario, to compare the behaviour of the two scenarios. Using the same approach as before we notice that due to the liquidity restriction we cannot use a simple model to combine the risky and riskless investments as a total amount, and hence the PDE is one order higher than before. We then model an investor who is investing in the hedge fund subject to the manager's optimal portfolio decisions, with similar mathematical tools as before. Comparisons between the investor's expected utility of wealth and the utility of having the money invested in the risk-free investment suggests that, in some cases, the investor is paying more to the manager than the return he is receiving for having invested in the hedge fund, compared to a risk-free investment. For that reason we propose a strategic game where the manager's action is to allocate the money between the two assets and the investor's action is to add money to the fund when he expects profit. The result is that the investor profits from the option to reinvest in the fund, although in some extreme cases the actions of the manager make the investor receive a negative value for having the option.

La numérisation 3D permet de générer des représentations numériques très réalistes et fidèles géométriquement aux surfaces réelles. Cependant, cette fidélité géométrique, obtenue à l'aide d'un sur-échantillonnage de surfaces, augmente considérablement le volume de données générées. Les maillages ainsi produits sont donc très denses, et peu adaptés aux différents supports de visualisation, de transfert, de stockage, etc. La représentation semi-régulière des surfaces permet de diminuer le volume nécessaire à la représentation de ces maillages denses, et possède des qualités bien connues en matière de représentations multi-échelles et de compression. Cette thèse a pour objectif d'optimiser la chaîne de numérisation 3D classique en améliorant l'échantillonnage des surfaces tout en conservant la fidélité géométrique, et en court-circuitant les étapes fastidieuses qui conduisent à une représentation semi-régulière. Pour cela, nous avons intégré dans un système stéréoscopique, l'échantillonnage en disques de Poisson qui, grâce à ses propriétés de bruit bleu, réalise un bon compromis entre sous- et sur-échantillonnage. Ensuite, nous avons généré un mailleur semi-régulier, qui travaille directement sur les images stéréoscopiques, et non sur une version remaillée des nuages de points habituellement générés par ces systèmes. Les résultats expérimentaux montrent que ces deux contributions génèrent de façon efficace des représentations semi-régulières, qui sont géométriquement fidèles aux surfaces réelles, tout en réduisant le volume de données générées.

Nowadays, 3D digitization systems generate numeric representations that are both realistic and of high geometric accuracy with respect to real surfaces. However, this geometric accuracy, obtained by oversampling surfaces, increases significantly the generated amount of data. Consequently, the resulting meshes are very dense, and not suitable to be visualized, transmitted or even stored efficiently. Nevertheless, the semi-regular representation due to its scalable and compact representation, overcomes this problem. This thesis aims at optimizing the classic 3D digitization chain, by first improving the sampling of surfaces while preserving geometric features, and secondly shortening the number of required treatments to obtain such semi-regular meshes. To achieve this goal, we integrated in a stereoscopic system the Poisson-disk sampling that realizes a good tradeoff between undersampling and oversampling, thanks to its blue noise properties. Then, we produced a semi-regular meshing technique that directly works on the stereoscopic images, and not on a meshed version of point clouds, which are usually generated by such 3D scanners. Experimental results prove that our contributions efficiently generate semi-regular representations, which are accurate with respect to real surfaces, while reducing the generated amount of data.

▼ In this thesis we give an overview of recent stochastic Lagrangian models and present a new particle model for turbulent dispersion and chemical reactions. Our purpose is to investigate and assess the feasibility of the Lagrangian approach for modelling the turbulent dispersion and chemistry interactions. We emphasise the numerical aspects and advantages of the method for the implementation on (massively) parallel computers. In Chapter 1, a general introduction to the topic of modelling turbulent transport and chemistry is given. Before we direct most of our attention to Lagrangian modelling, we give an overview of Eulerian models for turbulent transport and chemistry, like direct numerical, large eddy and Reynolds averaged simulations in Chapter 2. We begin the treatment of Lagrangian modelling with a detailed survey of the stochastic Lagrangian theory (Chapter 3). In stochastic models turbulence is considered as a stochastic process.Accordingly the concentration is a stochastic function and can be modelled by its mean, its uctuations and higher statistical moments. By generating many one-particle trajectories we are able to predict the mean concentration only. The second moment of the concentration can be inferred from the statistics of particle pair trajectories. Models based on one-particle trajectories are discussed in Chapter 4. In the same chapter we give a short overview of the problems that arise if one attempts to formulate relative di usion models and present Kaplan and Dinar's model to describe the trajectories of pairs of uid particles. There are to our knowledge only a few Lagrangian models for the turbulent transport of reactive constituents. In Chapter 5 an overview of these models is given. We also propose some improvements in these models and present a new one-particle model. We present, in Chapter 6 a new two-particle model for turbulent transport and chemistry interactions. The results of the new two-particle model for transport and chemistry are discussed in Chapter 7. In Chapter 8 the parallel implementation aspects of Lagrangian models and of the new two-particle model in particular are discussed. Finally the conclusions from the present study are summarised in Chapter 9.

[pt] As ligações viga-pilar desempenham uma função fundamental para a determinação do comportamento real de estruturas de aço e mistas. Portanto torna-se necessária uma avaliação muito criteriosa das reais características geométricas e mecânicas destas ligações, substituindo as tradicionais considerações idealizadas, rígida e flexível, pela modelagem semi-rígida em aço ou mista. Com a intenção de dar continuidade do estudo sobre ligações semirígidas em aço e desenvolver um estudo sobre as ligações semi-rígidas mistas, inicialmente foi realizada uma revisão bibliográfica destes assuntos apresentando os parâmetros a serem desenvolvidos nesta pesquisa. Foi implementado computacionalmente um sistema de análise e dimensionamento capaz de avaliar o comportamento estrutural destas ligações a partir da informação das propriedades geométricas de ligações viga-pilar executadas com placa de extremidade em aço e mistas, produzindo uma base de dados para um projeto estrutural mais seguro. Um projeto experimental foi desenvolvido para avaliar o caminho de transmissão de esforços, através de modelos experimentais de laboratório, na forma de ensaios pull-out modificados, adaptando-se este ensaio para regiões de momento negativo, onde a laje de concreto se encontra fissurada, obtendo um ensaio capaz de produzir resultados que contribuam com o desenvolvimento da pesquisa de ligações semi-rígidas em aço e mistas.

[en] The beam-column connections play a key role in determining the actual behavior of steel and composite structures. Therefore it is necessary a very careful assessment of the real geometrical and mechanical characteristics of these joints, replacing the traditional idealized considerations, rigid and flexible for modeling semi-rigid steel or composite. With the intention of continuing the study of semirigid connections in steel and develop a study on the semi-rigid composite connections, was initially performed a revision of startled presenting the parameters to be developed in this research. We have implemented a computational system analysis and design capable of evaluating the structural behavior of these joints from the information of the geometric properties of beamcolumn connection with end plate executed in steel and composited, producing a database for a structural design safer. An experimental project was designed to evaluate the path transmittance of efforts, through experimental models of laboratory tests in the form of modified pull-out, adapting this test for regions of negative moment, where the concrete slab is cracked, obtaining a test that can produce results that contribute for the development of research of semi-rigid connections in steel and composite.
