A variant of the direct simulation Monte Carlo (DSMC) method, referred to as direct
molecular simulation (DMS), is used to study oxygen dissociation from first principles. The …

The Modified Marrone-Treanor (MMT) chemical kinetics model [1] was developed recently
using ab-initio quantum chemistry data. The MMT model has been implemented into a CFD …

This paper reports on measurements of freestream nitric oxide (NO) rotational and
vibrational temperatures and partial pressures, collected in the Caltech T5 reflected shock …

Fully kinetic, vibrationally kinetic, and continuum solvers with varying model fidelity are used
in this work to model the high-temperature relaxation of air in 7230 and 15,000 K adiabatic …

This paper presents molecular dynamics calculations of vibrational energy transfer and
nonequilibrium dissociation in O 2+ O collisions. The O 2+ O interactions are modeled using …

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 …

Nonequilibrium chemical kinetics plays an important role in hypersonic flows [2, 3]. There
exist a variety of chemical kinetics models for CFD in the literature, based on a range of …

We report on measurements of rotational and vibrational temperature, velocity, and
concentrations of nitric oxide (NO) in freestream flows at the T5 reflected shock tunnel at …

We report on near-body measurements of temperature and nitric oxide (NO) concentration in
the hypersonic flows around a cylindrical test article in the Caltech T5 reflected shock tunnel …

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