Abstract
A preferential vibration-dissociation coupling model is incorporated into a radiatively coupled viscous shock layer code that also includes chemical, radiative, and thermal nonequilibrium. Stagnation point flow profiles are obtained for several flight conditions and are compared with experimental data. The code is further modified to calculate a separate vibrational temperature for each diatomic species, and comparisons are made between this multiple vibrational temperature model and the single vibrational temperature model. Adjustments in molecular absorption coefficients are also made for several diatomic species. Based on comparisons with experimental data, very little preferential dissociation behavior is present in the flight conditions analyzed.
