Simulation of vibrational energy transfer and dissociation in O 2–N 2 collisions is conducted
using the quasi-classical trajectory method on an ab initio potential energy surface …

An implementation of the Macheret-Fridman (MF) dissociation model for the direct simulation
Monte Carlo (DSMC) method is developed in this work. The model maintains the …

The energy transfer, dissociations, and chemical reactions between O2 and N2 play an
important role in the re-entry process of aircraft and many atmospheric, combustion, and …

Hypersonic flows are often characterized by strong chemical nonequilibrium [1, 2]. The
chemical evolution of the flow has a first-order effect on various quantities of interest …

The supersonic mode in hypersonic boundary layers has recently been shown to achieve a
larger peak growth rate than the traditional second mode in particular circumstances …

Hypersonic vehicles operate at speeds in excess of Mach 5, producing extreme
temperatures and nonequilibrium flow phenomena. A principle challenge associated with …

The ability of the Navier–Stokes equations to capture the effects of strong chemical and
thermal nonequilibrium on gas composition in a manner similar to the direct simulation …

In this paper, we report a quasi-classical trajectory study of the internal energy state
specificity of dissociative O2+ N2 collision rates computed at high temperatures on an …

Thermochemical nonequilibrium widely exists in supersonic combustion, cold plasma and
hypersonic flight. The effect can influence heat transfer, surface ablation and aerodynamic …
