Thermochemical nonequilibrium is one of the most challenging issues when dealing with
hypersonic flows experienced by objects (space vehicles, meteoroids, space debris) at …

This work deals with the simulation of hypersonic flows past a copper sphere by using a
finite-rate catalysis model coupled with either a state-to-state (StS) or a multitemperature …

The presence of shocks in scramjet internal flows introduces nonequilibrium of internal
energy modes of the molecules. Here, the effect of vibrational nonequilibrium on key …

Transition rates in O 2–O collisions for each vibrational and rovibrational state are generated
by means of the quasi-classical trajectory method using potential energy surfaces of different …

Recent progress in state-resolved kinetic models of thermal relaxation and dissociation of
oxygen based on high-fidelity transition rate coefficients is presented. Specifically, three …

The dissociation rate of nitrogen for the reaction N 2+ N 2→ N 2+ N+ N was calculated as a
function of a translational, vibrational, and rotational temperature, each ranging from 6000 to …

An important research direction in hypersonic aerothermochemistry is associated with the
modeling of thermal and chemical nonequilibrium from first principles using quantum …

We report in this paper an investigation on energy transfer processes from vibration to
vibration and/or translation in thermal and subthermal regimes for the O2+ N2 system …

Simulation of vibrational energy transfer and dissociation in O2–N2 collisions is conducted
