First steps in development of a translational non equilibrium model using maximum entropy principle
… the steps taken in the development of a model for flows that are in translational non-equilibrium. The backbone of the model relies on Boltzmann equation for gases as a starting point. Three mathematical tools - domain decomposition, moment methods similar to method of weighted residuals …

Modeling for anaerobic fixed-bed biofilm reactors
Biofilm models, developed by previous researchers, were incorporated with an equilibrium model to study the physical and chemical aspects of the anaerobic fixed-bed biofilm reactors. In order to investigate the mechanism of equilibrium in an anaerobic biofilm reactor, a non-equilibrium model was …

Maximum entropy quadratic model to characterize chemical non-equilibrium in re-entry flows
This thesis presents the study of an advanced non-equilibrium model for state-specific chemical kinetics based on method of moments. The focus of this project is on the rovibrational chemical kinetics of the N2-N system. Internal excitation, dissociation, recombination and energy transfer …

Flux-split algorithms for flows with non-equilibrium chemistry and thermodynamics
… flow situations, when finite-rate chemistry and non-equilibrium thermodynamics greatly affect the physics of the problem. Two flux-vector-split algorithms, of the Steger-Warming and of the Van Leer type, and one flux-difference-split algorithm of the Roe type are established and utilized for the …

Carbon Dioxide Capture with K-Promoted HTLC at High Temperature
… the second objective was to further develop a non-equilibrium kinetic model to account for both temperature and pressure dependencies to make the model useful for cyclic adsorption process modeling and design. The temperature dependence was established by correlating a series of experiments …

Multi-scale modeling of laser induced breakdown in non-equilibrium plasmas
This dissertation discusses the modeling of breakdown of gases under nano-second laser discharges, the plasma kernel dynamics, the plasma core decay, and the subsequent post-dischargee hydrodynamics, together with some of its engineering applications (e.g., flow control and ignition of combustible …
