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 …

A Computational Model for Two-Phase Ejector Flow
A CFD model to simulate two-phase flow in refrigerant ejectors is described. This work is part of an effort to develop the ejector expansion refrigeration cycle, a device which increases performance of a standard vapor compression cycle by replacing the throttling valve with a work-producing …

An Original Method for Computing Complex Non-Premixed Flows in Chemical Equilibrium
<p>A novel method for computing chemical equilibrium reactions in three-dimensional reacting fluid flows is introduced in this paper. The originality of the method is that continuity equations are solved for the atomic densities rather than for the molecular species densities, as is the case for …

Development of a high-fidelity thermochemical model for the O2+O system using direct simulation Monte Carlo
… investigation of reactions in a thermo-chemical non-equilibrium condition, which is especially with the application with the flows encountered during atmosphere entry/re-entry missions. The particle-based computational method, direct simulation Monte Carlo(DSMC), has been widely used for the …

Contributions to the Understanding of Turbulent Boundary Layers Over Curved Walls
… how the statistics and structure of a near-canonical boundary layer were modified along the Suboff afterbody and 2. Determine whether these alterations stemmed from pressure gradient, lateral curvature, or longitudinal curvature depending on their relative spatial patterns. The pressure …

Transport of Heat and Momentum In Non-Equilibrium Wall-Bounded Flows
<p>Transport of momentum and heat in non-equilibrium wall-bounded flows is studied analytically and experimentally to better understand the underlying physics, transition dynamics, and appropriate flow scaling in non-equilibrium flows. Non-equilibrium flows, in which the mean flow time scales are …
