Abstract
The interaction between nitrogen vibrational-translational relaxation with different chemistrymodels in a hypersonic
shock is studied. The vibrational-translational transition models considered include the Larsen–Borgnakke, Schwartz-
Slawsky-Herzfeld, and forced harmonic oscillator models; and the nitrogen monoxide formation reaction was studied
using the total collision energy chemistry model and reaction cross sections obtained from quasi-classical trajectory
simulations. Using direct simulation Monte Carlo solutions that incorporate these models, improved nitrogen monoxide
spectral radiation modeling was performed by employing quenching rates from recent experiments. Comparisons of
electronic state populations and the corresponding radiative spectra for the different vibrational-translational and
chemistry models are presented, and it is shown that the vibronic spectral structure of the nitrogen monoxide radiation
could provide a way to test the fidelity of the internal energy transfer and chemistry models.
