▼ A comprehensive second law analysis of combustion for a range of conditions and fuels was completed. Constant pressure, constant volume and constant temperature combustion processes were examined. The parameters studied were reactant temperature, reactant pressure, equivalence ratio and the fuels themselves. In addition, the contribution and relative significance of the various components (thermo-mechanical, reactive and diffusion) to the mixture availability was examined. Also, the effect of reactant mixture dissociation was incorporated into the combustion analysis. It was found that for similar initial conditions, constant pressure combustion and constant volume combustion exhibited similar trends. For constant temperature combustion, the trend is significantly different from the constant pressure and constant volume combustion, with almost the entire reactant availability being destroyed due to combustion at lower temperatures. Amongst the parameters examined, reactant mixture temperature had the most significant effect on the fraction of availability destroyed during combustion. The percentage availability destroyed reduced from 25 to 30% at 300 K to about 5% at 6000 K for constant pressure and constant volume combustion processes. The effect of the reactant mixture pressure on the fraction of availability destroyed was more modest. The values for the percentage availability destroyed for pressures ranging from 50 kPa to 5000 kPa were found to lie within a range of 5%. The effect of equivalence ratio on the fraction of reactant mixture availability destroyed was also documented. In general, it was found that the destruction of availability decreased with increasing equivalence ratios. This value, however, accounts for the availability due to fuel like species in the product mixture. Therefore, for practical applications, combustion of the stoichiometric mixture would be preferred over the rich equivalence ratios. It was found that the fraction of reactant availability destroyed increased with increasing complexity of the fuel??s molecular structure. In addition, it was shown that the diffusion availability terms is small and may be neglected, while the reactive availability and thermo-mechanical availability are more significant.

▼ The selection and design of any biomass combustion system is primarily determined by the combustion characteristics of the fuel. It is the thermal energy released by the combustion reactions which drives the entire process. Thus, understanding of the combustion characteristics or oxidation behaviour of the biomass may lead to successful biomass combustion process at larger scale. This study investigates the oxidation of rice husk, palm fibre and palm fibre char using an evolved gas analysis (EGA) technique. This EGA technique involves heating the biomass and char from 100°C to 500°C at a controlled rate with a constant flow of air. The evolved gas was continually analysed for its oxygen, carbon monoxide and carbon dioxide contents. A series of EGA experiments was carried out using rice husk, palm fibre and palm fibre char. By studying how the evolved gas composition varies with temperature, the many oxidation reactions occurring may be grouped into just three simultaneous and competing reaction regimes known as low, medium and high temperature oxidation. The different reaction regimes may be decoupled and the key kinetic parameters such as activation energy for each regime were determined. These not only demonstrated the potential of the EGA technique as a tool to study the biomass oxidation but also provide insights into the effects of variations in pressure, oxygen partial pressure and heating rate for both of the biomass and biomass char. The oxidation behaviour of both the rice husk and palm fibre was found to be substantially different to that observed for the palm fibre char. The principle difference observed was the number of peaks present in a plot of oxygen consumption versus temperature - two peaks were formed for the both of biomass but EGA experiments consistently shows only one peak for palm fibre char. It was found that the oxygen partial pressure of the oxidising gas in the combustion cell significantly influences the oxidation behaviour. Increasing the partial pressure of the oxygen typically moved the reactions to lower temperatures. The activation energies and peak oxygen consumption temperatures were all found to be linear functions of the oxygen partial pressure of the gas supplied to the reactor. Varying the total pressure of the reaction vessel while keeping the oxygen partial pressure constant did not lead to any significant variations in the reactions parameters.

Electricity from biomass and biomass–derived fuels has become an attractive and viable alternative energy source. Alkali metals, mainly sodium and potassium, together with other ash forming inorganic components in biomass, increase fouling, slagging, and high temperature corrosion of heat transfer surfaces in boilers thus reduces efficiency during biomass combustion. Future biomass-to-electricity facilities will benefit from increased efficiencies, by incorporating integrated gasification combined cycle systems that use biomass syngas directly in gas turbine. These systems will have even lower tolerances for alkali vapor release, because accelerated erosion and corrosion of turbine blades results in shorter turbine life. One solution to the fouling and slagging problem is to develop methods of hot gas cleanup to reduce the amount of alkali vapor. A detailed understanding of the mechanism of alkali metals release during biomass gasification could greatly benefit the development of hot gas cleanup technology. In this study, thermodynamic equilibrium predictions were made of the distribution and mode of occurrence of gaseous chlorine and alkali metals of three types of biomass (corn stover, switch grass, and wheat straw) in combustion and gasification processes. The influence of temperature, pressure, and air-fuel ratio was also evaluated. Results show that the percent stoichiometric air has limited influence on the speciation of chlorine and potassium during combustion. However, the influence of the percent stoichiometric air is significant during gasification. Increasing percent stoichiometric air enhances the formation of vapor HCl and KOH as well as reduction in vapor KCl and K2Cl2. In biomass combustion and gasification, increasing pressure increases vapor HCl and K2Cl2 and reduces the amount of vapor KCl and KOH. At higher temperatures (>1100K), the gaseous alkali species increased greatly.

▼ The design of reliable combustors is a crucial aspect of propulsion and energy production applications: a faulty engine could cost human lives and millions (if not billions) of dollars. In practice, it is unreasonable to expect all devices to be extensively tested for all operating conditions that they will experience. The set of possible conditions is large, and the state of the device itself can evolve during its lifetime. Yet, deviations from normal behavior, or extreme events, should be appropriately accounted for during the design and the operation of the combustor. In this work, a theoretical approach for the prediction of extreme events is presented. A classification of failures is proposed, and predictive questions that pertain to the failures are identified. This framework guides the work done in this thesis and is tailored to pave the way of future developments that are not addressed here. Two different routes for the prediction of extreme events are explored: one which attempts to characterize the dynamics of a system, and one which attempts to quantify the statistics of a failure. The target of the first route (dynamical system approach) is to provide an understanding of the process through which a failure occurs so that the design can be adjusted to inhibit a failure. To this end, the Lyapunov analysis is examined in the context of turbulent reacting and inert flows from different angles. The convergence of the Lyapunov exponents with respect to the numerical discretization is examined. Lyapunov exponents are used to quantify the complexity of the attractor and the Lyapunov vectors are used to characterize the response of the flow to perturbations. The objective of the second route (statistical approach) is to quantify the statistics of the failure. In particular, the main focus is on obtaining the probability of a rare extreme event. This is achieved by estimating the trajectory leading to a rare event. The uniqueness of this work lies in the comprehensive approach to extreme event prediction that is developed. While the work is mostly illustrated with target problems relevant for turbulent combustion, it has applications in other complex and high-dimensional problems.

▼ Dispatchable low carbon electricity has been identified as a key requirement for low carbon electricity systems because these systems must provide reliable electricity services to an increasing portion of the world’s population while utilising an increasing share of nondispatchable assets such as renewable and nuclear generators. Fossil fuel generators can provide dispatchable low carbon electricity by leveraging post-combustion carbon capture technologies assuming post-combustion capture (PCC) plants can operate in a flexible and efficient manner. This thesis explores the connection between solvent analysis techniques and the optimal operation of PCC plants with a particular focus on process optimisation and control under flexible and transient conditions. The connection between solvent analysis measurements and PCC plant process control and optimisation strategies is established. An ideal set of analysis technique criteria is established for flexible post-combustion capture plants. Currently available solvent analysis techniques are surveyed and evaluated against the ideal set of criteria. Specific weaknesses of current techniques are highlighted and two novel solvent analysis techniques are introduced to address these weaknesses. The first provides continuous amine concentration and CO2 loading measurements at process flow conditions by inferring solvent chemical composition from physical properties. This method was evaluated by deploying an instrument prototype to a post-combustion pilot plant to continuously analyse solvent during a test campaign which simulated flexible plant operation. The measurement results were compared against industry standard solvent analysis techniques and the inferential technique was found to produce sufficient measurement accuracy and sensitivity while providing a faster, lower cost and more robust measurement technique. The second technique combines the strengths of several currently available CO2 loading techniques to measure CO2 gas evolved from an acidified solvent under vacuum conditions. The technique was found to provide superior measurement accuracy and sensitivity compared to currently available methods when measuring lab standard solutions. The integration of these novel analysis techniques into advanced process control systems is proposed and future method improvements are suggested.

▼ This dissertation concerns the analysis and modeling of turbulence dynamics in turbulent combustion. In certain regimes of turbulent combustion, dilatation (volumetric expansion) induced by chemical heat release can result in significant modification of turbulence dynamics, leading to the failure of most common turbulence models used in predictive simulations. In this dissertation, the physical mechanisms of interaction between chemical heat release and turbulence are analyzed, scaling theories for the regime dependence of these effects are confirmed, and new turbulence models are introduced to account for these interactions. Numerical simulation forms the foundation of the analyses in this dissertation. Using a common planar jet configuration, a range of turbulent combustion regimes is accessed via Direct Numerical Simulation (DNS). In order to conduct these simulations accurately and efficiently on large-scale parallel computers, advanced numerical algorithms are introduced. These schemes improve the accuracy of state-of-the-art schemes and reduce the computational cost by approximately a factor of two. In nonpremixed combustion, heat release effects on turbulence are observed at low turbulent Reynolds number (the ratio of inertial forces to viscous forces), but the impact on turbulence model validity is minimal due to the greatly reduced turbulence intensity. In premixed combustion, scaling theories for the dependence of dilatation effects on Karlovitz number (the ratio of the flame time scale to the Kolmogorov time scale) are confirmed for the first time in turbulent shear flows. Algebraic combinations of limit-state turbulence models are proposed to account for counter-gradient transport in low Karlovitz number premixed combustion. A variable "efficiency function" controls the regime dependence of counter-gradient effects, and these models are verified a priori using the DNS databases. The algebraic approach successfully captures counter-gradient transport in the flame-normal direction, but the linear nature of these models precludes them from capturing other effects of heat release including effects of instantaneous flame motion. Finally, a new statistical description of turbulence is introduced by conditioning on an independent flame coordinate. Turbulence statistics obtained in this framework explicitly account for effects of flame motion and chemical heat release. Budgets of conditional mean velocity and turbulent kinetic energy are computed, and modeling implications are discussed. Advisors/Committee Members: Mueller, Michael E (advisor).

▼ In this thesis, we investigate the properties and linear stability of homogeneous premixed planar propagating combustion waves in one spatial dimension. In particular, we investigate travelling premixed combustion waves in a diffusional-thermal model with a two-step competitive exothermic reaction mechanism in which both reactions are exothermic and the same reactive material provides the feed for both exothermic reactive steps. Such reactions have direct relevance to the combustion of MeCH₂, where Me is either titanium or zirconium. Combustion waves in two-step competitive exothermic-reaction schemes are investigated for various fuel types, includinggaseous, porous and solid fuels, under both adiabatic and nonadiabatic conditions. In addition, the Evans Function Method is employed to analyze the linear stability of the combustion waves. The purpose of the study is to investigate how the properties of the combustion waves vary as various parameter values change. Of particular interest are those parameters describing the ratios of the activation energies, pre-exponential factors and enthalpies of the two reactions, the Lewis number of the reactants, the heat-loss parameter and ambient temperature. As well as the transitions from stable to unstable planar wave solutions, various bifurcations are analyzed.The properties and linear stability of the travelling-wave solutions from two-step competitive exothermic reactions are more complicated that those from single-step exothermic reaction; in particular, regions of bi-stability exist: different solutions coexist for the same parameter values. When bi-stability does not exist, the behaviour of the combustion waves is similar to that from the single-step reaction. When bistability does exist, two stable branches, a fast branch with fast flame speeds and a slow branch with slow flame speeds, can co-exist. The transitions between the fast and slow branches are observed by altering the fuel temperature profiles. The steady travelling waves become unstable due to the existence of Hopf bifurcations and there are three possible scenarios. The conditions of the existence of bi-stability are discussed.

Thesis Ph. D. Michigan State University. Chemistry 2014.

Maximizing the efficiency of the combustion process requires the ability to sense oxygen levels over a broad range of concentrations with fast response times under rapidly varying conditions of pressure and temperature to maintain the correct fuel/oxygen ratio in real-time. Quenching of the luminescence from organometallic compounds by oxygen has been used to develop a number of fiber-based sensors. A major drawback of these organometallic indicators for combustion applications is that the chromophores degrade with time, have a limited operational temperature range, typically room temperature ±25°C, and lack long-term reliability. This work investigates luminescent molybdenum clusters based on Mo6Cl12 were as replacements for organometallic indicators. A study of the high temperature stability of Mo6Cl12 in air revealed irreversible changes in the optical absorption spectrum at T >250°C and a loss of the red luminescence characteristic of the pristine clusters. Thermal aging experiments run in air and under nitrogen point to oxidation of the clusters as the cause of the change in optical properties. X-ray powder diffraction measurements on samples annealed at 300°C under controlled conditions are consistent with oxidation of Mo6Cl12 to form MoO3. Optical and thermal aging experiments show that K2Mo6Cl14*1H2O, the alkali metal salt of Mo6Cl12, has higher thermal stability and remains luminescent after long-term aging in air at 280°C. Methods were developed for depositing K2Mo6Cl14*1H2O-incorporated sol-gel films on planar and optical fiber substrates by dip coating and spray coating. The mechanical properties of the films depended on the film thickness; thin films were stable, but cracks often formed in the thicker films needed for sensors. This problem was addressed using two strategies: altering the components of the sol-gel solutions used to embed the clusters and by devising a composite approach to sensing layers where a slurry of fully cured sol-gel particles containing K2Mo6Cl14*1H2O in a sol-gel "binder" were deposited on substrates. The optical properties of a large number of fiber sensors were tested up to 102°C, with the best results obtained using the K2Mo6Cl14*1H2O/sol-gel composite sensing film. Fiber M demonstrated quenching of 4-6× between <0.001% and 21.1% (v/v) oxygen at 23, 42, 60, 81 and 102°C respectively. The sensor switches abruptly between two well defined levels with a response time of less than 10 s. Quenching of the cluster luminescence by oxygen obeys a two-site Stern-Volmer relationship based on measurements of fiber 121 at 42, 73, and 102°C, with sensitivity decreasing as temperature increases. The cycle-cycle variations for six cycles between nitrogen and oxygen at 58°C for fiber 45 corresponds to an uncertainty of ±1% to ±15% in oxygen concentration over the entire measurement range from 21.1% (v/v) to 2.1% (v/v) oxygen respectively. The long-term performance data from cycling fiber 70 between <0.001% (v/v) and 21.1% (v/v)…

Cette thèse a pour but l’étude de la rotation de l’écoulement des grandes échelles dans deux configurations. La première configuration se concentre sur l’effet de la rotation de l’écoulement sur une flamme laminaire. Elle est stabilisée dans le sillage d’un cylindre. La rotation de l’écoulement est introduite en faisant tourner le cylindre autour de son axe. La simulation numérique directe (Direct Numerical Simulation (DNS)) montre que la rotation du cylindre rompt la symétrie des deux branches de la flamme. La fonction de transfert de flamme (Flame Transfer Function (FTF)), obtenue grâce à l’inversion de Wiener-Hopf, indique qu’un faible taux de rotation réduit le gain de la FTF et donc la flamme devient presque insensible aux perturbations acoustiques à une fréquence donnée. De plus, il est démontré que cette diminution du gain est due à une interférence destructive des fluctuations de chaleur produites par les deux branches de la flamme. La fréquence à laquelle le gain de la FTF devient presque nul est ajustable par la vitesse de rotation du cylindre. Cette étude suggère que le contrôle de la symétrie de la flamme pourrait être un outil de contrôle en boucle ouverte des instabilités thermoacoustiques. Dans le cas de la deuxième configuration, la rotation de l’écoulement est induite par une instabilité hydrodynamique, aussi nommée Precessing Vortex Core (PVC) dans un système d’injection de carburant industriel. Des expériences et des simulations aux grandes échelles (Large Eddy Simulation (LES)) montrent que l’écoulement non-réactif dans l’injecteur pri- maire peut être décomposé en une contribution moyenne et un PVC. Cette instabilité hydro- dynamique est étudiée par l’analyse de stabilité linéaire (Linear Stability Analysis (LSA)) en utilisant deux approches différentes (locale et BiGlobale). Les résultats de l’expérience, de la LES et de la LSA démontrent que le montage d’une tige centrale à l’intérieur de l’injecteur stabilise le PVC. De plus, le même injecteur industriel est étudié dans le cas d’un écoule- ment réactif par LES. Les résultats démontrent que la flamme stabilise le PVC. L’analyse de stabilité BiGlobal montre que le gradient de densité dans le front moyen de la flamme a un effet important sur l’amortissement du PVC. Enfin, l’impact de la tige centrale est également étudié pour le cas réactif. La tige centrale impacte marginalement la forme globale de la flamme, mais a un effet positif sur l’accrochage de la flamme dans la zone de combustion pauvre. En comparant deux cas par LSA, celui avec la tige et celui sans la tige, les résultats suggèrent que la tige augmente considérablement l’amortissement du PVC. Cela pourrait causer une diminution de la turbulence dans l’écoulement et empêcher l’extinction de la flamme et donc expliquer l’influence bénéfique de la tige sur la stabilisation de la flamme.

▼ Combustion synthesis (CS) or self-propagating high temperature synthesis (SHS) is an energy saving, effective technique for production of a variety of advanced micron and nano-scale materials with properties that are superior to those manufactured by conventional methods. Recent developments and important breakthroughs within the CS field have shown its high level of diversity. In this work special attention has been paid to the gasless heterogeneous combustion joining (CJ) (rapid reactive welding) and topics related to it such as mechanical activation (MA) of reactive systems, kinetics study of high temperature reactions and CS of anti-oxidation (AO) coatings. Joining dissimilar materials is of increasing interest for a wide range of military and industrial applications. For example, in combat fields, joining materials has received great attention in recent years due to weight reduction of both vehicle components and structures. In particular, layered ceramic/metal-alloy (i.e., SiC/5083 Al-alloy) composites show considerable potential for lightweight armor applications. However, ceramics and metal-alloys exhibit very different physical, mechanical and metallurgical properties, which make joining process problematic. To solve this problem a rapid gasless reactive CJ technique is developed. A novel scaled-up CJ apparatus was designed and built. A reactive powder mixture (Ti+C) was used as a joining layer to bond SiC to 5083 Al-alloy. It showed that bonding of SiC to 5083 Al-alloy was achieved with formation of a transitional interface that was compatible with those components to be joined. Several joining schemes were utilized and both micron-sized (up to 10 μm) and submicron-sized (500 nm) joints were accomplished by CJ. A number of gasless heterogeneous powder mixtures were utilized as a joining medium. It is critical to control reactivity and structure of such mixtures. In this work the influence of mechanical activation on the microstructures and ignition characteristics of such systems were investigated. The experimental approach is based on a high energy ball milling (HEBM) technique. Results show that short-term HEBM is an effective tool to tailor the microstructure and ignition characteristics of reactive powder mixtures and the MA-systems can be further utilized for CJ of various materials. Another technique, known as electro-thermal analysis (ETA), which allows one to evaluate the kinetics of high temperature rapid reactions before and after MA processes (Ni-Al system), was also employed. It is shown that a short-term MA treatment decreased the apparent activation energy for reaction between Ni and Al from 38 ± 1 (kcal/mol) to 25 ± 3 (kcal/mol). A decrease of ignition temperature of reactive mixtures was observed after HEBM. This feature allows initiation of joining process at a much lower temperature. Combustion joining of refractory materials (carbon/carbon, C/C, composites) was accomplished using mechanically activated systems. An important industrial application is… Advisors/Committee Members: Eduardo E. Wolf, Committee Member, Y. Elaine Zhu, Committee Member, Alexander S. Mukasyan, Committee Chair, Paul J.

▼ This thesis details the design and construction of a Low Temperature Co-Fired Ceramic (LTCC) micro combustion system. The design of the combustor requires a detailed analysis of the flame’s operational properties and stability. To this end, an analytic model was created to address these concerns. These results were used in conjunction with a detailed numerical analysis to determine the stable operating range of the combustors. The combustion of gaseous fuels requires a device with a lower bound on the channel feature size. This lower limit for combustion corresponds to the minimum quenching distance of the specific fuel being used and usually corresponds to the upper end of silicon MEMs processing techniques and the lower end of meso-scale production processes. This millimeter size range represents the normal feature size range for the LTCC tape system. A potential material imposed restriction to using LTCC is the relatively low temperature operating range when compared to the adiabatic flame temperatures encountered in the combustion of gaseous fuels. To address this concern an analytic model of the heat transfer from a simple straight channel device is presented. This model allows for the analysis of the thermal loads in the substrate as well as provides insight into the effects of the channel geometry on the stability of the flame. Several experimental devices were designed and tested in accordance with the predictions of the analytic model. These devices have similar geometric configurations with different characteristic lengths to explore the feasible operating regimes of the LTCC micro combustor. This allows for the validation of the flame stability margins and heat transfer properties predicted by the analytic model. Infrared imaging allows for the mapping of the device surface temperature and provides a correlation mechanism to the analytic model. The results of the experimental testing show the same trending characteristics predicted by the analytic analysis. However, a detailed numerical analysis is needed to fully capture the quantitive power production capabilities of the device.

▼ The internal combustion engine is synonyms with the automobile since its invention in late 19th century. The internal combustion engine today is far more advanced and efficient compared to its early predecessors. An intense competition exists today amongst the automotive OEMs in various countries and regions for stepping up sales and increasing market share. The pressure on automotive OEMs to reduce fuel consumption and emission is enormous which has lead to innovations of many variations in engine and engine-related technologies. However, IC engines are in existence for well more than a century and hence have already evolved to a highly refined state. Changes in IC engine are therefore largely incremental in nature. A deterrent towards development of an engine configuration that is significantly different from its predecessor is the phenomenal cost involved in prototyping. Thus, the only viable alternative in exploring new engine concepts and even optimizing designs currently in operation is through extensive use of CAE. In light of published work in the field of analysis of IC engines, current research effort is directed towards development of a rational methodology for arriving at a weight-optimized engine design, which simultaneously meets performance of various attributes such as thermal, durability, vehicle dynamics and NVH. This is in contrast to the current methodology adopted in industry, according to which separate teams work on aspects of engine design such as combustion, NVH (Noise, Vibration and Harshness), acoustics, dynamics, heat transfer and durability. Because of the involvement of heterogeneous product development groups, optimization of an engine for weight, which can have a significant impact on its power-to-weight ratio, becomes a slow process beset with manual interventions and compromise solutions. Thus, following the traditional approach, it is quite difficult to claim that an unambiguous weight-optimized design has been achieved. As a departure from the practiced approach, the present research effort is directed at the deployment of a single multi-physics explicit analysis solver, viz. LS-DYNA - generally known for its contact-impact analysis capabilities, for simultaneously evaluating a given engine design for heat transfer, mechanical and thermal loading, and vibration. It may be mentioned that only combustion analysis is carried out in an uncoupled manner, using proven phenomenological thermodynamic relations, to initially arrive at mechanical and thermal loading/boundary conditions for the coupled thermo-mechanical analysis. The proposed methodology can thus be termed as a semi-integrated technique and its efficacy is established with the case study of designing a single cylinder air-cooled diesel engine from scratch and its optimization.

▼ The massive global use of combustion and the large exergy destruction in fuel combustion which is typically 20% to 30% of the useful energy highlight the importance of seeking for more exergy-efficient combustion. This dissertation pursued quantitative understanding of the reasons for the irreversibilities, i.e., their cause, location and magnitude, and recommended approaches for reducing them. This was studied by two different approaches: 1) the conventional and most frequently numerical way, the intrinsic analytical method (IAM) based on the solution of the system differential equations, which requires complex computation, and 2) the novel heuristic finite increment method (HFIM) that solves a system of algebraic equations, which is an orders-of-magnitude computationally easier approximation. The results demonstrated that the overall exergy destruction ratio computed by the IAM (22.58%) and the HFIM (19.6% to 22.3% for the 14 paths) agreed well for the studied adiabatic isobaric hydrogen/air combustion. The fractions of the individual contributors (chemical reaction, heat transfer, mass transfer and viscous dissipation) to the overall exergy destruction in the two approaches, however, were quite different. The IAM predicted that the chemical reaction was the dominant contributor (at 80.56%), while the HFIM predicted that the heat transfer was the dominant one (at 47.4 % to 72.1%). The difference was explained, for the first time, and it was because the HFIM assumed the combustion occurring in a prescribed path that made the chemical reaction rate at low temperature higher than reality. This established the connection of the two different approaches. Ways to reduce irreversibilities, by the sensitivity analysis in the IAM, comprised of reducing the excess air coefficient, increasing the inlet temperature, making the combustor walls as close as possible to adiabatic and optimizing the inlet velocity. Methods to decrease irreversibilities, by analyzing 14 hypothetical paths in the HFIM, were applying stoichiometric oxygen combustion and heat recirculation from high-temperature to low-temperature chambers. This dissertation also compared the exergy destruction results for similar combustion conditions computed by the HFIM and the IAM for the first time. The comparison enabled the identification of the hypothetical paths in the HFIM which were the closest to reality.

▼ Turbulent combustion modeling is a complex computational problem. Several factors including the large number of unknowns and equations, stiffness in the chemical source terms, and turbulence-chemistry interaction combine to make simulation of turbulent combustion a grand-challenge problem. Direct Numerical Simulation (DNS) is the most accurate approach to simulate turbulent combustion processes. This approach solves for the full set of chemical variables in the system and is fully resolved in space and time; therefore, it is computationally expensive. There are several models trying to increase the efficiency of turbulent combustion modeling with reducing the number of unknowns, reducing the stiffness of the problem, or decreasing the resolution with the least error possible. In this research, two novel models are introduced to increase the efficiency of turbulent combustion modeling in the Large Eddy Simulation (LES) context. Each method tries to make the modeling more efficient in a different aspect. The first one is a method to reduce the number of species equations that must be solved, via application of Principal Component Analysis (PCA). This technique provides a robust methodology to reduce the number of species equations by identifying correlations in state-space and defining new variables that are linear combinations of the original variables. Here we first present results from \emph{a priori} studies to show the strengths and weaknesses of such a modeling approach. Results suggest that the PCA-based model can identify manifolds that exist in state space which are insensitive to filtering, suggesting that the model is directly applicable for use in Large Eddy Simulation. Second, we explore the invariance of the manifolds identified by PCA with respect to the problem's parameters. In order to simulate a turbulent process using a PCA-based model, the PCA mapping should be trained using an empirical dataset. This \emph{a priori} study clarifies the important factors for choosing a training dataset. Results indicate that, for given reactant compositions and temperatures, over modest ranges of Reynolds number where the combustion regime does not change dramatically, PCA-derived manifolds are invariant with respect to Reynolds number. It also further confirms PCA manifolds invariance to the filter width, which is an interesting result that suggests the applicability of the model in LES. Finally, an \emph{a posteriori} study of PCA is presented as a combustion model applied to a nonpremixed CO/H₂ temporally evolving jet flame with extinction and reignition. As a basis for comparison, results from detailed chemistry calculations are compared with the PCA-transport results to verify the model and evaluate its performance. Invariance of the model's error to the Reynolds number, the number of retained PCs, the PCA scaling factor, and the training dataset is evaluated in this research. The second proposed method is a new explicit variable-density pressure projection method with a focus on transient low-Mach-number…

▼ Combustion synthesis leverages the exothermic reaction between a fuel and an oxidizer to provide the energy needed to form crystalline refractory oxides. In many cases combustion syntheses are less energy intensive and require fewer processing steps than traditional ceramic oxide processes. However, the properties of materials produced by combustion syntheses can depend on many processing parameters, such as the type of fuel used, the fuel to oxidizer ratio, coordinating characteristics of the fuel, the rate of heating the reactant solution. This work reports the results of process optimization and materials characterization studies of three ceramic oxides: yttrium aluminum garnet (YAG), lanthanum zirconate (LZO) and yttrium borate (YBO). Cerium and/or europium dopants were incorporated into these three host lattices to enhance their photoluminescent (PL) properties. The effects of process parameters on the crystallinity, composition, and PL emission intensity of the synthesized materials were investigated. We show that mixing urea and citric acid fuels decreases the PL intensity of YAG:Ce1% compared to using either pure urea or pure citric acid. Characterization of the material found that the material synthesized using only citric acid contained the most YAG phase and that the decrease in PL intensity is likely due to dopant segregation. We show that the heating rate used to raise the reactant solution to the ignition temperature also affected the crystallinity of the synthesized material. Thermogravimetric analysis and differential scanning calorimetry identified a heating rate that produced the maximum heat of combustion. Transmission electron micrographs of the synthesized material show that heating rates affect the morphology of the material. The YBO process optimization involved adding additional fuel and oxidizer to compensate for the lack of a boron-based oxidizer and included a post-synthesis anneal. The effect of proton irradiation on the PL of these materials was tested. The PL of YAG and LZO was not affected by a fluence of 1x10¹⁶ protons/cm², however the PL intensity of YBO decreased with doses of 1x10¹⁴ protons/cm² and above. Advisors/Committee Members: D. Greg Walker (committee member), Kenneth Debelak (committee member), M. Douglas LeVan (committee member), Bridget R. Rogers (Committee Chair).

▼ A dynamic data-driven application system (DDDAS) is a recently formalized architecture that integrates simulation with dynamically assimilated data, multiscale modeling and computation via completion of a two-way feedback loop between model execution and the data acquisition modules. The perception layer of DDDAS requires precise feature extraction from dynamic data, multi-scale (both spatial and temporal) data analysis and hierarchical sensor fusion, which are capable of real-time execution. This dissertation proposes hierarchical approaches that tackle different aspects of the perception layer of DDDAS, based on the concept of symbolic time series analysis (STSA). STSA is a nonlinear feature-extraction tool that is applied on dynamic data by constructing probabilistic finite state automata (PFSA) via symbolization based on an alphabet size. Along with proposing a supervised alphabet size selection algorithm, the dissertation develops optimal STSA algorithms that capture the texture of individual temporal data (by Generalized D-Markov machines) and that of the causal cross-dependence (by ×D-Markov machines) from one temporal data set to another with reduced dimensionality. The aforementioned patterns are aggregated to construct a spatio-temporal pattern network (STPN) from a sensor network and it is pruned via an information-theoretic approach for fault diagnosis in distributed systems. Finally, a hierarchical architecture named multiscale symbolic time series analysis (MSTSA) is formalized, where a semantic finite length learning-and-inferencing mechanism is stacked to capture the multi-timescale nature of DDDAS events in real time. In addition to extensive validation by complex simulation experiments, the proposed techniques have been applied on experimental data for early detection of Lean Blow out (LBO), and thermo-acoustic instability in combustors and the performance is compared with state-of-the-art results. A hierarchical framework is developed combining deep learning and STSA with the objective of autonomously tracking the temporal evolution of coherent structures that are distributed in the flame during combustion instability. MSTSA has been successfully implemented in real-time activity recognition from noisy sensor data for border surveillance scenarios. It is envisioned that the general contributions, made in this dissertation, will be useful for many other potential application areas in DDDAS paradigm, such as weather system causality understanding, smart grid and buildings, distributed energy systems, situation awareness in ISR (intelligence, surveillance and reconnaissance) missions, material damage prediction and future ground and air transportation systems.

▼ Aerosolized nanoparticles represent both great potential for the development of emerging technologies and one of the biggest challenges currently facing our planet. In the former case, aerosol-based synthesis techniques represent one of the most cost-effective approaches to generating engineered nanoparticles having applications that range from medicine to energy. In the latter case, aerosolized soot is the second largest forcing factor after carbon dioxide in climate change models and contributes significantly to asthma, bronchitis, and various other respiratory illnesses. The increased predominance of engineered nanoparticles also presents significant environmental and health risks due to various toxicological effects. In any of these cases, robust characterization is critical to the function and regulation of these nanoaerosols. Time-resolved laser-induced incandescence (TiRe-LII) is well-suited to meeting this challenge. Since its inception in the 1980s, TiRe-LII has matured into a standard diagnostic for characterizing soot in combustion applications and, increasingly, engineered nanoparticles synthesized as an aerosol. The in situ nature of the technique makes it well-suited to probe in-flame soot formation and the fundamentals of nanoparticle formation. Moreover, its cost-effectiveness and real-time capabilities make TiRe-LII particularly well-suited as an avenue for online control of nanoparticle synthesis. TiRe-LII involves heating nanoparticles within a sample volume of aerosol to incandescent temperatures using a short laser-pulse. Following the laser pulse, the nanoparticles return to the ambient gas temperature via conductive and evaporative cooling. The magnitude of the peak spectral incandescence signal can be used to derive the particle volume fraction, while the temperature decay of the nanoparticles can be used to infer thermophysical properties, including the nanoparticle size, thermal accommodation coefficient (TAC), and latent heat of vaporization. Data analysis requires the use of spectroscopic models, used to convert the observed incandescence to a volume fraction or nanoparticle temperature, and heat transfer models, used to model the changes in the nanoparticle temperature over the duration of a signal. These models have evolved considerably over the past two decades, increasing the interpretive power of TiRe-LII. Nevertheless, there are several factors that impede further improvements to the reliability of TiRe-LII derived quantities. Several anomalies have been observed in measured signals collected from both engineered nanoparticle and soot, ranging from faster-than-expected temperature decays to inconsistencies in measurements between laboratories and experimental conditions. Resolving these differences is crucial to improving the robustness of TiRe-LII both as a combustion and engineered nanoparticle diagnostic. However, this first requires the development of advanced analysis tools that allow for a better understanding of nanoscale physics and the uncertainties associated with model…

Research Doctorate - Doctor of Philosophy (PhD)

The increasing emissions of such greenhouse gases as carbon dioxide (CO₂) foster the need for the removal of CO₂ from gas streams, especially from coal-fired power stations. One of the common technologies of CO₂ Post Combustion Capture (PCC) is reversible chemical absorption using amine-based solvents. For PCC to be efficient, the rate of the absorption of CO₂ in aqueous solution has to be fast in order to minimise the spatial requirements of the absorber column. Therefore, the catalysis of CO₂ hydration/dehydration is of utmost interest. In this project, series of inorganic oxoanions and carbonic anhydrases were studied by stopped-flow spectrophotometry with the aim of elucidating their chemistry in the interaction with CO₂ and finding a good catalyst for PCC. Additionally, it is crucial to closely monitor the PCC process by developing on-line analyses. Fourier-transform infrared (FT-IR) spectroscopy is a promising spectroscopic tool for this purpose thanks to its robustness and ease of data interpretation. The second focus of this project is to investigate the feasibility of using FT-IR spectroscopy for on-line analysis for PCC application by monitoring the kinetics of the reaction of bicarbonate with MEA by this spectroscopy. The outcomes of this project would benefit the development of effective CO₂ capture facilities, contributing to the reduction of greenhouse gas emissions. The limitations in terms of time consumption and complexity of the traditional method to study an enzymatic system inspired the development of a novel kinetic procedure to analyse the efficiency of enzymatic catalysis, i.e. the Michaelis-Menten parameters. The principle of this method is that the kinetics of an enzymatically catalysed reaction is observed from the initial high substrate concentration until the substrate is entirely consumed. The course of the reaction process is followed via the solution pH changes. This approach is different from the integration method in which the determination of the substrate or product concentration is required, which is difficult. The new procedure has been applied to the study of urea hydrolysis by jack bean urease. Not only have the Michaelis constant and catalytic constant been determined with ease, the catalytic mechanism of urease was further clarified. This novel method is applicable to the study of many other enzymatic systems.
