Continuum breakdown assessment and state-based transport modeling for non-equilibrium hypersonic flows
… as well as rovibrationally resolved transport collision integrals for the O+O2 (atom-diatom) system; (ii) develop a reduced order/coarse-grained StS transport methodology. The generalized Chapman-Enskog (GCE) approach serves as the primary underlying principle of this work. The first aspect of …

Consistent treatment of transport properties of weakly-ionized gas mixtures in DSMC
… of mass, momentum and energy during binary collision processes between the simulated particles. The details of the collision processes, and therefore, the transport properties are dictated by the collision cross-section models employed in DSMC. In the DSMC method, phenomenological models are …

Uncertainty quantification applied to the analysis and design of a hypersonic inflatable aerodynamic decelerator for spacecraft reentry
… subject to uncertainties in the binary collision integrals of the transport properties, chemical kinetics, non-Boltzmann radiation modeling, and the freestream conditions. The uncertainty analysis for fluid-structure interaction modeling is conducted to quantify the uncertainty in the …
