The present study is aimed in providing a framework for applying different continuum models
of relaxation processes in carbon dioxide flows. Kinetic equations for the distribution function …

The objective of this study is to examine various combinations of vibration-chemical coupling
models in high-temperature air and oxygen flows behind shock waves. Simulations are …

A model for simulating postshock conditions using only state-resolved kinetic data of ab
initio accuracy is presented. The quasi-classical trajectory method is used to compute a …

In the paper, the results of numerical modeling are presented of the 3D turbulent flows in a
channel with backward-facing step, and argon jets injected into the supersonic crossflow …

Nonequilibrium flows of air components behind reflected shock waves are systematically
studied on the basis of several theoretical models for the rate coefficients of fully coupled …

We present direct molecular simulations (DMSs) of rovibrational excitation and dissociation
of oxygen across normal shock waves. These are the first atomistic simulations of normal …

The thermochemical nonequilibrium model for oxygen, O 2, in collisions with atmospheric
gas species, is modified in the present work. The vibrational relaxation time with high …

The validation of recently developed models of vibration-dissociation coupling is discussed
in application to numerical solutions of the Navier–Stokes equations in a two-temperature …

An extension to the normal shock relations for a thermally perfect, calorically imperfect gas,
modelling the vibrational excitation with an anharmonic oscillator model and including the …

This work evaluates high-fidelity vibrational-translational (VT) energy relaxation and
dissociation models for pure O 2 normal shockwave simulations with the direct simulation …
