▼ FLNG cooling water outfalls can be characterized as high momentum buoyant jets, relatively close to the surface. The buoyant jet trajectories, spreading rates and surface distribution very much depend on the jet outflow characteristics. A study with the CFD software OpenFOAM has been carried out into the mixing and transport processes of buoyant jets. It is shown that OpenFOAM can be used to model the three dimensional trajectories of buoyant jets and their far-field buoyant plume distribution. Two dominant mixing processes are the result of the high initial jet momentum. First, the high momentum jet results in large turbulent jet entrainment rates. Second, the relatively shallow high momentum jets result in large horizontal surface currents. These currents horizontally advect the buoyant plume into the far-field and result in steep vertical velocity gradients, which induce vertical mixing of the buoyant plume. The momentum length scale, Lm proves to be an important parameter to characterize buoyant jets. The momentum length scale represents a distance along the jet trajectory, where buoyancy effects become dominant over initial jet momentum. For these jet characteristics it is found that the dimensionless surface temperature rise follows a logistic distribution function to the momentum length scale, after the point of surface impingement. The relative surface temperature results become constant for increasing values of the momentum length scale. This is the result of increased mixing by the jet turbulent entrainment and steep vertical velocity gradient. From the logistic distribution an empirical relation is found which can accurately predict the surface temperature rise as a function of the outfall velocity, outfall diameter, outfall temperature, outfall angle and distance from the jet orifice. The outfall depth appears to have no significant influence on the surface temperature rise for the conditions used in this study. The empirical equation proves to give reliable results for distances larger than 1.5 times the value of the momentum length scale and jet submergence smaller than 7.5 times the jet diameter. The robustness of the equation is also tested for extreme value outfall scenarios. The equation overestimates the temperature rise for small outflow diameters, combined with high initial jet temperatures. For other considered extreme values, the equation proves to give reliable results. Moreover, it is also demonstrated that the standard k-epsilon turbulence closure can be successfully used to model the buoyant jet centerline velocities, jet trajectories, spreading rates and centerline dilution rates of a round turbulent buoyant jet.

Cette thèse s'inscrit dans le contexte de la simulation numérique et l'analyse des écoulements compressibles, notamment en géométrie complexe ou mobile. Dans ces situations, la mise en place d'un maillage représentant correctement lesolide sans perte de précision des méthodes de discrétisation s'avère difficile. Une alternative est de travailler en maillage cartésien quelque que soit la géométrie du domaine d'écoulement en introduisant une approche aux frontières immergées.Dans ce contexte, on propose une amélioration et extension d'une méthode formulée pour la simulation des écoulements incompressibles. Les deux principales caractéristiques du modèle proposé sont d'une part l'intégration d'un nouveau terme de forçage des vitesses qui prend en compte les effets de pression et d'autre part l'intégration d'un nouveau terme de correction de température dans le traitement de l'équation de l'énergie.Cette méthode a été intégrée dans deux solveurs compressibles du code OpenFOAM : SonicFOAM et RhoCentralFOAM. La validation a été effectuée en considérant différents cas de complexité croissante sur des corps 2Dfixes et mobiles, pour lesquels on a fait varier les nombres de Mach et de Reynolds. De plus, des cas mettant en jeu des transferts de chaleur pariétaux ont été étudiés. Les résultats ont été comparés à un grand nombre de données numériques et expérimentales issues de la littérature.Enfin, des études sur des configurations plus complexes tridimensionnelles ont été mises en place. Les bifurcations de régime d'écoulement de la sphère ont été investiguées quand le nombre de Mach augmente. Une sphère avec des parois non-adiabatiques a été également analysée. Une géométrie réaliste de drone a été simulée en régime compressible.Ces analyses mettent en évidence de nombreuses caractéristiques favorables de la méthode des frontières immergées en termes de précision, de flexibilité et de coût de calcul.

This thesis is related to the numerical simulation and the analysis of compressible flows, especially in complex or mobile geometry. In these situations, the establishment of a mesh correctly representing the solid with out loss of precision of discretization methods is difficult. An alternative is to use Cartesian mesh independently of the geometry of the flow domain by introducing an immersed boundary approach. In this context, we propose an improvement and extension of a method formulated for the simulation of incompressible flows. The two main characteristics of the proposed model are on the one hand the integration of a new velocity forcing term which takes into account the effects of pressure and on the other hand the integration of a new term of temperature correction in the treatment of the energy equation. This method has been integrated in two compressible solvers of OpenFOAM code: SonicFOAM and RhoCentralFOAM. The validation was carried out by considering different cases of increasing complexity on fixed and mobile 2D bodies, for which the Mach and Reynolds numbers were varied. In addition, cases involving parietal…

▼ Existing studies suggested a number of possible contributing factors to dry inclined cable galloping, including the axial flow forming on the leeward side of the inclined cable and the emergence of critical Reynolds number. The current study aims at investigating the role of cylinder orientation and Reynolds number in this phenomenon. A combination of the detached eddy and large eddy simulations was conducted to study the fluid structure around and aerodynamic force coefficients of a stationary circular cylinder normal to or inclined against the oncoming flow. The developed numerical models have been validated using existing numerical and experimental data. The effect of axial flow, in terms of the cylinder orientation represented by the attack angle (0 ◦ , 30 ◦ , 45 ◦ , 60 ◦ ), and the Reynolds number (3900, 1.4E4 , 1E5 , 1.4E5 , 2.8E5 ) have been discussed in detailed. A numerical study has been performed to indirectly examine the effect of the axial flow via a perforated splitter plate. Visualization of the fluid structure shows that a secondary flow forms on the leeward side of the circular cylinder when it is inclined, and the separated shear flow becomes more stable as cylinder orientation increases. Results indicate that the inclination of the circular cylinder would cause a near-zero span-wise averaged lift force due to the span-wise delay of the sectional cross-flow force coefficient. The sectional lift force coefficient is found to become more disorganized when the flow enters the critical Reynolds number régime in general. Within this critical range, the span-wise averaged lift force coefficient shows a peak amplitude that significantly differs from that in the subsequent shedding cycles when the attack angle is less than 45 ◦ . Results of the perforated splitter plate manifest that with the decrease of the splitter plate perforation ratio, a stronger interruption on the interaction between the two separated shear flows was found.

▼ A continuum stress transport model of platelet aggregation from the literature [14], [16], [15], and [18] is presented and solved numerically. The model is a single-scale reduction of a multi-scale model and utilizes the incompressible Navier-Stokes equations with a Newtonian constituative relationship to govern blood ow. Other eld variables including platelet and chemical activator concentrations exist with partial dierential equations governing their transport. The platelet aggregation model is closely related to the model of the viscoelastic Oldroyd-B uid, which is discussed. The focus of this thesis is on the numerical solution of the Oldroyd-B equations and the equations comprising the platelet aggregation model using a nite volume formulation within an existing open source Computational Fluid Dynamics platform. Pressure-velocity coupling is achieved using the PISO Algorithm while the remaining model equations are solved sequentially. In the rst class of simulations, the ow of an Oldroyd-B uid is solved within a two dimen- sional planar domain. The viscous and elastic properties of the uid are varied in an eort to observe the model's resulting behavior. Exact solutions for the transient and steady-state ow of an Oldroyd-B uid are used for the purpose of validating the numerical approach. Numerical solutions are observed to correspond well with exact solutions for a range of parameter sets. Solution divergence is observed under certain conditions, specically for uids with high Weis- senberg numbers and elastic moduli. In the second class of simulations, the platelet aggregation model is solved within the same domain as the Oldroyd-B simulations. Clot growth is observed but solution divergence occurs in the presence of growth of the model's stress tensor eld. By limiting certain model parameters it is shown that numerical stability can be improved. Using this approach, the sensitivity of results to various model parameters is investigated. Finally, a preliminary investigation of the application of the model to the clinically important case of clot growth within stagnant and recirculating ows is presented.

▼ Homogeneous charge compression ignition (HCCI) and stratified charge compression ignition (SCCI) engines potentiallyoffer high fuel economy and low emissions. Practical problems need to be overcome, however, and several of them areaffected by or may be alleviated/controlled by stratification of the charge, whether deliberate mixture-stratification by directinjection, or thermal stratification resulting from wall-heat transfer. This thesis therefore seeks to develop and evaluate acomputational model of the combustion process in HCCI and SCCI engines that is capable of simulating the effects of chargestratification. The basis of the modelling is an approach known as conditional moment closure (CMC), originally developedfor nonpremixed jet flames, which reduces errors associated with closure of chemical source terms by conditioning themon a variable upon which they principally depend. This thesis builds on previous work to adapt CMC to HCCI and SCCIengines which considered thermally stratified ignitions in an environment free of walls. In two important steps towards acomplete CMC model of an SCCI engine, the present thesis considers first mixture-stratified ignition and second thermallystratified ignitions in the presence of walls. In the former case the baseline CMC model considers mixture fraction as theconditioning variable, while in the latter it considers total enthalpy. Extensions of these models by considering second orderclosure, double conditioning, and conditioning on reacting scalars are also considered.Two sets of two-dimensional direct numerical simulation (DNS) are employed to evaluate performance of the CMCmodels. The first DNS data-set simulate ignitions in SCCI-like thermochemical conditions with compositionally stratifiedn-heptane / air mixtures in a constant volume representing the bulk gas at top dead centre (TDC) of an SCCI engine.The second DNS data-set considers the effect of wall heat transfer on auto-ignition of thermally stratified hydrogen/airmixtures in a two-dimensional channel representing the TDC of an HCCI engine. The first DNS data-set is parametrised byfluctuations in mixture composition and temperature, whereas the second set is parametrised by temperature fluctuations.Using the first DNS data-set, and the mixture-fraction CMC model, a posteriori tests of the model, which is implementedin an open-source computational fluid dynamics (CFD) package known as OpenFOAMR , reveals an excellent agreementbetween the CFD-CMC solver and the DNS data-set for the cases with low levels of stratification, whereas deviations fromthe DNS are observed in cases which exhibit high level of stratifications. A subsequent a priori analysis reveals that thereason for disagreement is failure of the first-order closure due to the high level of conditional fluctuations. A second-orderclosure is also shown to fail to improve the results and it is only double conditioning that provides a satisfactory closure forthe reaction rates.Using the second DNS data-set modelling ignition in a channel with wall heat… Advisors/Committee Members: Hawkes, Evatt, Mechanical & Manufacturing Engineering, Faculty of Engineering, UNSW, Bolla, Michele, Aerothermochemistry and Combustion Systems Laboratory, ETH Zurich, Talei, Mohsen, Department of Mechanical Engineering, University of Melbourne, Kook, Shawn, Mechanical & Manufacturing Engineering, Faculty of Engineering, UNSW.

▼ L'un des principaux leviers technologiques permettant le développement industriel de process de production énergétique renouvelable et à haute efficacité, consiste en l'élaboration d'une solution innovante de stockage de l'énergie. Ce système de stockage doit permettre de lisser la période de production et ainsi de suivre au plus près les besoins des consommateurs. Parmi les solutions existantes, le stockage thermique par chaleur latente présente de nombreux avantages qui font qu'aujourd'hui il fait l'objet de plusieurs travaux de recherche et de développement. Cette technologie est basée sur le principe que certaines classes de matériaux, appelés matériaux à changement de phase (MCP), libèrent (transition liquide/solide) ou accumulent (transition solide/liquide) de l'énergie lorsqu'ils sont soumis à un changement de phase. En amont du développement d'un design de stockage, il est essentiel de comprendre et de maitriser les processus thermiques entrant en jeu lors des phases de fusion et de solidification du matériau et cette compréhension passe par le développement de modèles numériques adaptés aux problématiques rencontrées. Dans le cadre de ce manuscrit, la filière technologique qui nous intéresse est celle des centrales solaires à concentration. Porté par l'ADEME dans le cadre du projet STARS (Stockage Thermique appliqué à l'extension de pRoduction d'énergie Solaire thermodynamique), le travail réalisé au sein du LaTEP consiste à analyser les performances d'une solution de stockage via la modélisation de cette dernière en considérant les phénomènes thermiques et hydrauliques. Le travail de modélisation est effectué à l'aide du logiciel de CFD libre de droit OpenFOAM dans lequel est développé et implémenté, par le laboratoire, un module dédié au problème qui nous concerne, à savoir la résolution eulérienne (maillage fixe) des équations de conservation pour un fluide incompressible, en présence d'un changement de phase solide-liquide dominé par des mouvements convectifs (convection-dominated phase change). Concernant les problèmes de transition de phase, diverses méthodes mathématiques et numériques ont été développées pour rendre compte finement de la physique de ces phénomènes. Après avoir effectué une revue de ces dernières dans la première partie du manuscrit, nous avons sélectionné deux formulations que nous avons implémenté dans OpenFOAM. Une fois ce travail réalisé nous avons taché de comparer les résultats renvoyés par ces différentes formulations en les confrontant aux résultats expérimentaux disponibles dans la littérature. Cela nous a permis d'une part de nous conforter dans l'utilisation de nos solveurs et sur la pertinence des résultats obtenus avec ces derniers et d'autre part de mettre en évidence les écarts entre les solutions renvoyées par chaque formulation. Fort de ce constat, nous avons souhaité évaluer l'impact de l'équation d'état utilisée pour relier l'enthalpie et la température, indispensable à la fermeture thermodynamique du système d'équations. Cette comparaison s'est faite par la… Advisors/Committee Members: Bedecarrats, Jean-Pierre (thesis director).

▼ Measuring the temperature distribution inside the rotary kilns, using thermocouples for instance has proven to be difficult due to the harsh operating conditions of the kiln. Numerical modelling of turbulent combustion and the associated physical phenomenon thus proves to be an indispensable tool towards predicting the kiln operating conditions. The purpose of the present work was to make a step towards modelling the cement rotary kiln used by Almatis B.V. in Rotterdam for the production of calcium-aluminate cement. The detailed mathematical model of the rotary kiln would be developed using the open source CFD toolbox OpenFOAM. The main advantage of OpenFOAM is that, contrary to most of the commercial CFD software, it is license fee free and allows access to the source code, which was also the motivation behind this work. To accurately model the Almatis kiln the following important phenomenon have to be taken into account: turbulent non-premixed combustion of hydrocarbon gases in the burner, radiative heat transfer distribution in the kiln and, the conjugate heat transfer through the furnace walls. In the present work the new solver implemented in OpenFOAM for turbulent combustion and radiation modelling was validated using the benchmark Sandia Flame D test case. There was good agreement seen between the results from simulations and experimental data for the Sandia Flame D test case indicating the adequacy and accuracy of the implemented transient solver and its readiness for further combustion application development. Due to the very complex geometry of the Almatis Kiln the relatively simple geometry of the Burner Flow Reactor (BFR) was considered for further simulations. The simulation results obtained for the Burner Flow Reactor (BFR) were compared with the commercial package ANSYS Fluent for consistency. The OpenFOAM toolbox was evaluated in two stages of increasing complexity: isothermal(cold) flow simulation and non-premixed gas combustion simulation using a turbulent incompressible flow solver. The cold flow comparison gave almost identical results for both OpenFOAM and ANSYS Fluent. However the reacting flow results showed varying agreement with ANSYS Fluent. The mass fraction of species showed good agreement but the temperature profile showed some deviations. With more stringent global NOx emission standards, predicting NOx formation in industrial furnaces is now a priority. The CFD modelling of pollutant NOx formation was considered in the present work. A new solver in OpenFOAM was developed for thermal NO prediction. The solver was validated with the ANSYS Fluent NOx post-processing utility using the Burner Flow Reactor geometry. The effectiveness of NOx reduction mechanisms including the variation of air to fuel equivalence ratio and flue gas re-circulation (FGR) was demonstrated using the Burner Flow Reactor test case. From this study it was concluded that OpenFOAM is a promising toolbox for modelling turbulent combustion and can be used for predicting the operating conditions of complex industrial… Advisors/Committee Members: Lahaye, D.J.P., Vuik, C., Keijzer, M..

▼ Flow-induced vibration (FIV) plays an important role in the nuclear industry. In nuclear power plants (NPP), the FIV may cause fatigue problems, stress corrosion cracking, possible failure modes and fretting wear. This in return can lead to nuclear safety issues and substantial stand-still costs due to unplanned outages. It is therefore important to asses this phenomena early in the design process. Most of the experiments or analytical models used to predict FIV, are over simplified or cover only a single operation condition. Therefore using a combination of Computational Fluid Dynamics and Computational Solid Mechanics to model FIV can play an important role for the complex industrial applications. In the present work the numerical simulations are performed using the OpenFOAM Extend open source code, in which both the fluid and structural dynamics are computed using the Finite Volume (FV) method. Moreover, a partitioned approach was implemented, in which the exchanges between the fluid and structure solver take place. This was done through the use of the Interface Quasi Newton with Inverse Jacobian from a Least-Squares (IQN-ILS) coupling method. To gain the confidence of the available numerical methods, their validation is a necessary step that needs to be performed. Firstly the simulation of a well-known benchmark was performed using the IQN-ILS coupling method, where the deformation of an elastic flap, attached to a solid cylinder, is studied. Afterwards, the same coupling method was used to simulate the free vibration of a beam in a fluid and validated with experimental results. Lastly, the validated method was used to model the turbulence induced vibrations of a scaled version of a neutron flux measurement guide tube. From this study it has been found that the IQN-ILS coupling method can be used for strongly coupled problems. It has also been found that the mesh resolution and time step are important parameters for a correct estimation of the frequency and the damping of the oscillation.

In the global energy context, many solutions are suggested to change our energy dependence and solve our CO2 emission issues. For transportation, biofuels are mentioned as a possible alternative to fossil fuels. Yet many people argue that they could hardly replace oil. The low efficiency of the conversion from biomass to biofuels implies other main issues like land use and food competition. More simple conversion routes, using less energy-consuming steps, could be used. However, the major drawback is then the lack of compatibility with conventional engines. Instead of adapting the fuel to the engines, the opposite has been put forward recently with the homogeneous charge compression ignition (HCCI). This engine does not intrinsically rely on specific fuel properties. Given that a fairly homogeneous air-fuel mixture is prepared, it can be operated on a large range of fuels. In the first part of this thesis, we analyzed the esters produced from fermentable wastes by a biochemical process. We investigated experimentally the impact of these esters on the HCCI. In practice, the development of new engine concepts and the characterization of fuels rely more and more on numerical simulations. However, the accurate and comprehensive modelling of the highly nonlinear combustion processes of realistic fuels is extremely demanding. It requires detailed mechanisms that involve hundreds of chemical species and thousands of elementary reactions. The computational cost of these simulations is generally prohibitive. This implies, first, that fairly detailed CFD simulations can only include global mechanisms, which only describe the main steps of the combustion; and second, that very detailed reaction mechanisms are mainly limited to simplified systems. In the second part of this thesis, we developed a new method that significantly mitigates the computational burden of detailed chemistry in complex CFD simulations. The developed numerical method, named tabulation of dynamic adaptive chemistry (TDAC), speeds the CFD simulations up to 900 times with a very small simulation error compared to the direct numerical integration of the combustion mechanisms.

▼ In this work a cooling system connected to a reactor pressure vessel has been studied using the CFD method for the purpose of investigating the strengths and shortcomings of using CFD as a tool in similar fluid flow problems within nuclear power plants. The cooling system is used to transport water of 288K (15°C) into a nuclear reactor vessel filled with water of about 555K (282°C) during certain operating scenarios. After the system has been used, the warm water inside the vessel will be carried into the cooling system by buoyancy forces. It was of interest to investigate how quickly the warm water moves into the cooling system and how the temperature field of the water changes over time. Using the open source CFD code OpenFOAM 2.3.x and the LES turbulence modelling method, a certain operating scenario of the cooling system was simulated. A simplified computational domain was created to represent the geometries of the downcomer region within the reactor pressure vessel and the pipe structure of the cooling system. Boundary conditions and other domain properties were chosen and motivated to represent the real scenario as good as possible. For the geometry, four computational grids of different sizes and design were generated. Three of these were generated using the ANSA pre-processing tool, and they all have the same general structure only with different cell sizes. The fourth grid was made by the OpenFOAM application snappyHexMesh, which automatically creates the volume mesh with little user input. It was found that for the case at hand, the different computational grids produced roughly the same results despite the number of cells ranging from 0,14M to 3,2M. A major difference between the simulations was the maximum size of the time steps which ranged from 0,3ms for the finest ANSA mesh to 2ms for the snappy mesh, a difference which has a large impact on the total time consumption of the simulations. Furthermore, a comparison of the CFD results was made with those of a simpler 1D thermal hydraulic code, Relap5. The difference in time consumption between the two analyses were of course large and it was found that although the CFD analysis provided more detailed information about the flow field, the cheaper 1D analysis managed to capture the important phenomena for this particular case. However, it cannot be guaranteed that the 1D analysis is sufficient for all similar flow scenarios as it may not always be able to sufficiently capture phenomena such as thermal shocks and sharp temperature gradients in the fluid. Regardless of whether the CFD method or a simpler analysis is used, conservativeness in the flow simulation results needs to be ensured. If the simplifications introduced in the computational models cannot be proved to always give conservative results, the final simulation results need to be modified to ensure conservativeness although no such modifications were made in this work.

Os parques de estacionamento cobertos estão obrigados por legislação a terem sistemas de desenfumagem. Assim, nesta dissertação desenvolve-se um procedimento computacional para a analise e verificação de funcionamento de sistemas de desenfumagem com ventiladores de impulso para parques de estacionamento, recorrendo ao software de mecânica dos fluidos computacional OpenFOAM. Actualmente nos sistemas de desenfumagem de parques de estacionamento estão a ser aplicados ventiladores de impulso. Este tipo de ventiladores não estão contemplados pela legislação em vigor. Assim, para serem utilizados é necessário verificar se estes podem substituir as redes de condutas. A verificação do funcionamento de sistemas de desenfumagem com ventiladores de impulso e efectuada com recurso a programas de simulação de mecânica dos fluidos computacional. O software OpenFOAM não tem tutoriais para ventiladores de impulso. Assim, foi executado um procedimento para validação dos ventiladores de impulso. A validação consistiu em reproduzir-se uma experiência executada por Giesen et al. (2011). Executaram-se várias simulações com diferentes modelos de turbulência, verificando-se que o programa buoyantpimplefoam do software OpenFOAM ao utilizar o modelo de turbulência k -ɛ simulou quase na perfeição os ventiladores de impulso. O desenvolvimento do procedimento computacional foi executado para um parque de estacionamento com uma geometria bastante complexa. O parque de estacionamento foi criado com um software em 3D e posteriormente inserido numa malha j a criada com as dimensões exteriores do parque. Foram estipuladas as condições de fronteira e executou-se uma simulação de seiscentos segundos com parâmetros determinados previamente. O processamento da simulação teve a duração de aproximadamente oito dias. Dos resultados obtidos concluiu-se que o procedimento computacional apresentado simula adequadamente sistemas de desenfumagem em parques de estacionamento.

Covered car parks are obliged by legislation to have smoke control systems. Thus, this dissertation develops a computational procedure for the analysis and verification of operation of smoke control systems with jet fans for car parks, using the computational fluid dynamics software OpenFOAM. Currently jet fans are being applied in smoke control systems for car parks. This type of fans are not covered by existing legislation. Thus, for use it is necessary to determine whether these can replace ducts networks. The verification of operation of smoke control system with jet fans is made by simulation programs of computational fluid dynamics. The OpenFOAM software does not have tutorials for jet fans. Thus, it was performed a procedure for validating the jet fans. The validation consisted in reproduce an experiment performed by Giesen et al. (2011). Several simulations were executed using different turbulence models and it was verified that the program buoyantpimplefoam of software OpenFOAM using the k - ε turbulence model, simulated almost perfectly jet fans.

▼ Au cours des dernières années, la culture de microalgues est largement étudiée pour produire des biocarburants et d’autres produits de valeur en fixant le dioxyde de carbone de l’atmosphère, afin d’atténuer simultanément les effets du changement climatique et de réduire la dépendance à l’égard des carburants fossiles. En comparaison avec les systèmes ouverts, les photobioréacteurs fermés sont davantage utilisés en laboratoire, car ils permettent de contrôler avec précision les facteurs environnementaux tels que le pH, la concentration en éléments nutritifs, etc. Le principe de fonctionnement d’un photobioréacteur repose sur l’injection de bulles dans le milieu de culture pour (i) apporter du dioxyde de carbone aux cellules (ii)agiter le liquide. Par l’apport d’énergie lumineuse les cellules transforment le carbone inorganique en carbone organique par photosynthèse. Ainsi, les phénomènes physiques - l’écoulement, transfert de matière, transfert radiatif - et les phénomènes biologiques - photosynthèse, croissance cellulaire et mort - coexistent dans un photobioréacteur. Plus important encore, tous les phénomènes de base ne sont pas complètement indépendants les uns des autres. Des recherches récentes ont révélé que le comportement des bulles avait également une incidence directe sur le processus biologique. En raison du comportement significatif des bulles sur la productivité d'un photobioréacteur, la génération de bulles a été étudiée dans cette thèse au moyen de méthodes expérimentales et numériques.Dans l'étude expérimentale, nous avons conçu puis fabriqué un nouveau photobioréacteur afin d'étudier le bullage in situ. L’emploi d’une technique d’ombroscopie couplée à une caméra vidéo a permis l’enregistrement de séries de bulles. Les images traitées ont permis de mesurer des caractéristiques de bulles (fréquence, volume, facteur de forme). Le volume moyen de bulle et la fréquence de formation de bulles augmentent avec le débit de gaz. De plus, la distribution volumique monodisperse à faible débit devient de plus en plus polydisperse par l’accroissement de celui-ci. L’évolution de la forme des bulles lors de leur remontée dans le liquide a été évaluée par l’emploi de facteurs de forme. Ces facteurs diminuent avec la remontée des bulles et traduisent une déformation horizontalement. A débit élevé, les formes des bulles oscillent et coalescent plus fréquemment.La simulation du bullage a été réalisé par l’emploi d’une méthode Volume of Fluid (VOF) et d’une bibliothèque open source de mécanique numérique des fluides OpenFOAM. Ces choix de méthodes sont motivés en raison de la robustesse d'OpenFOAM en matière de simulation d'écoulements diphasiques rapportée dans la littérature. Une première étude numérique de simulation 2D a permis de déterminer les valeurs appropriées des paramètres numériques (nombre de Courant et la taille du maillage) tout en minimisant le temps de calcul par rapport à une pré-étude 3D. Sans surprise, nous avons déterminé que la taille des mailles devait être inférieure au diamètre de la buse pour… Advisors/Committee Members: Puel, François (thesis director), Pozzobon, Victor (thesis director).

Les barrages sur les rivières sont des obstacles à la migration piscicole. Les passes à poissons sont des ouvrages permettant aux espèces piscicoles de migrer, autorisant le rétablissement de la continuité écologique des cours d'eau. Le but de ce travail est de mieux comprendre les phénomènes physiques présents dans les passes à poissons naturelles. Ces passes sont des canaux à forte pente, équipé de rangées de plots en quinconce. Pour valider la pertinence de l'utilisation d'un modèle numérique, l'étude s'est limitée à l'écoulement autour d'un cylindre émergent placé au centre d'un canal. Le travail est décomposé en deux parties, une expérimentale et une numérique. La partie expérimentale est conduite dans un canal transparent de 4m de long, 0,4m de large et 0,4m de hauteur. Le diamètre du cylindre est 4cm et sa hauteur 20cm (toujours émergent). Les cas étudiés sont des débits de 5, 10, 15 et 20 l/s pour une pente nulle. Les nombres de Froude sont supérieurs à 0,5 et les nombres de Reynolds, basés sur le diamètre, sont compris entre 15000 et 50000. Les écoulements ont été filmés et un algorithme de suivi de particules (PTV) a été développé. Des zones de faibles vitesses existent, même pour Fr=1, pouvant assurer des zones de refuge pour le poisson. Les forces de trainée ont été mesurées sur le plot. Les évolutions des coefficients de trainée avec le nombre de Froude et des rapports de forme de l'écoulement autour du plot ont ainsi été évaluées. La partie numérique est réalisée avec OpenFOAM pour 4 cas d'étude (Q=10 et 20 l/s, S=0 et 2%) et 2 modèles de turbulence URANS, le RNG k-epsilon et le k-omega SST. Des modélisations en 2D ont également été faites avec Telemac 2D. Les résultats obtenus ont été comparés aux résultats expérimentaux. La modélisation 2D (shallow water) est exploitable seulement pour des nombres de Froude faibles, d'où la nécessité des modélisations en 3D. Le modèle komega SST semble le mieux adapté pour reproduire les écoulements étudiés. Les vitesses locales et les structures en 3D, non quantifiables expérimentalement, ont ensuite été décrites. Les influences du fond et de la surface libre sur le sillage apparaissent clairement en provoquant des vitesses verticales et des tourbillons à grandes échelles. Enfin, une simulation en LES a été conduite. Les structures tourbillonnaires sont mieux représentées que pour les modèles URANS, mais les temps de calcul sont grands.

The dams on rivers are fishes migration obstacles. The fishways are devices allowing the fishes to migrate, permitting the restauration of the ecological continuity. The aim of this work is to better comprehend the physical phenomena existing in the nature-like fishways. This kind of fishway is a high slope channel with staggered rows of blocks. To validate the relevance of the use of a numerical model, the study is limited to the flow around a single free surface piercing cylinder placed in the center of a flume. The work is in two parts, experimental and numérical. The experimental part is conducted in a transparent flume of 4m…

Les émissions polluantes à l’échappement des véhicules automobiles sont l'une des principales sources de pollution de l'air dans le monde d'aujourd'hui. Par conséquent, la législation a évolué afin de limiter ces émissions. L'un des aspects clés pour répondre consiste à bien maîtriser les échanges gazeux au sein du moteur à combustion interne. Cette amélioration est possible par l'optimisation de répartiteurs d'admission d'air. Dans ces répartiteurs d'admission d'air, la maitrise de l’écoulement de type tumble est une piste de progrès. Des volets sont installés à la sortie du répartiteur afin d'améliorer le rapport de tumble et donc le mélange air-carburant (VTS-Variable Tumble System). Une autre caractéristique de l'écoulement à l'intérieur des répartiteurs est l'effet des écoulements pulsés qui engendrent des fluctuations de pression assez importante. Par conséquent, le but de cette étude consiste à simuler le flux d'air pulsé à l'intérieur des répartiteurs d'admission et à identifier l'effet des pulsations de pression sur les composants actifs tels que les volets. Le travail de simulation dans la présente thèse a été effectué à partir du code open source CFD OpenFOAM. Dans un premier temps, l'effet des pulsations de pression est simulé à l'intérieur d'un tube d'acier et une méthodologie de simulation est développée. Les résultats de la simulation sont validés à partir de résultats expérimentaux obtenus sur un dispositif spécifique, le banc dynamique. Ensuite, des simulations ont été effectuées sur le répartiteur d'admission principal avec des volets. Tout d’abord, les simulations sont effectuées en régime permanent avec cinq positions d'ouverture différentes du clapet. Les forces et les moments agissant sur le volet en régime permanent sont obtenus et analysés. Puis, des simulations en régime transitoire avec des effets de pulsation de pression sont effectuées. Les résultats de la simulation instationnaire sont comparés aux résultats expérimentaux en termes de fluctuations de pression relative. Les effets des pulsations de pression sur les forces aérodynamiques et les moments agissant sur les volets sont analysés et commentés.

The exhaust emissions from automobiles are one of the major sources of air pollution in today’s world. Thence,research and development is the key feature of the modern automotive industries to meet strict emission legislation. One of the key aspects to meet these requirements is to improve the gas exchange process within internal combustion engines. It is possible by the design optimization of the air intake manifolds for internal combustion engines. One of such advancement in air intake manifolds is variable tumble systems (VTS). In VTS system, tumble flaps are installed at the exit of the manifold runner in order to improve tumble ratio and hence air-fuel mixing. Another feature of the flow inside the intake manifolds is pressure pulsation effect. Therefore, the aim of the Ph.D. work is to simulate the pulsating air flow inside the air intake manifolds and to identify the effect of the…

La datation par thermoluminescence des chauffes estcohérente avec la première période de fréquentation humaine il y a entre 37 000 et 33 500 ans. Lesarchéologues ont identifié deux types de thermo-altérations : des changements de couleur et desécaillages. Les changements de couleur résultent de réactions chimiques s'opérant à hautetempérature dans le calcaire, rendant la roche rouge ou grise. Des essais ex situ ont montré que lacouleur rouge survient après une chauffe de 10 minutes à 250 °C tandis qu'une température minimumde 350 °C est nécessaire pour la couleur grise. Le phénomène d'écaillage provient de fortes contraintesmécaniques dans la roche causées par la dilatation thermique et des processus thermo-hydriques. Deplus, des particules de suie recouvrent encore une partie des parois dans les zones altérées. À partirde ces indices, l'objectif de la thèse est de caractériser les feux de la Galerie des Mégacéros qui sesitue dans la partie profonde de la grotte. L'estimation des quantités de bois, du nombre de feux etde la capacité à alimenter les foyers pourrait aider les archéologues à faire des hypothèses sur lafonction de ces feux.Pour des raisons de conservation, seule la simulation peut reproduire des feux dans la géométrie de lagrotte sans nécessiter sa reconstitution. Cette étude consiste à construire une modélisation numériquede feux confinés et des impacts thermiques résultants. Un couplage fluide-structure est donc développéà partir de deux logiciels open source : OpenFOAM et Cast3m. Le premier effectue la simulation descénarios de feux grâce au module FireFOAM. Le second réalise les calculs thermo-mécaniques dansle massif. Afin d'étendre le champ d'application initial de FireFOAM, des modèles numériques ontété implémentés dans le code. Ceux-ci concernent le dépôt de suie, l'évaluation des risques, lacorrection des mesures par thermocouple et une condition limite en température. De plus, quelquesexigences de modélisation améliorant la qualité des résultats sont détaillées dans le manuscrit. Lemodèle ainsi développé est validé sur des feux expérimentaux exécutés dans une ancienne carrière decalcaire dont les dimensions sont proches de celles de la Galerie des Mégacéros. Du pin sylvestre, quicorrespond à l'essence dont sont issus les échantillons de charbon analysés de la grotte, est utilisécomme combustible. La combustion aboutit à des thermo-altérations analogues à celles observéesdans la grotte Chauvet-Pont d'Arc. Des écaillages et des changements de couleur se sont produits auplafond et aux parois de la carrière. La comparaison avec la simulation est effectuée à partir desmesures de températures, de vitesses ainsi que de concentrations de gaz et de particules.Le modèle numérique est ensuite appliqué à la simulation de feux dans la géométrie de la Galerie desMégacéros.… Advisors/Committee Members: Sirieix, Colette (thesis director), Lacanette, Delphine (thesis director).
