This work aims to develop a novel two-dimensional a posteriori method for analyzing shock tube flows under nonequilibrium thermochemistry conditions.
Developed a two-dimensional method for viscous, reacting gas analysis in shock tube flows.
Removed requirement for self-similar boundary-layer correlations by fixing shock location with an additional equation.
Conducted comparisons with reference cases of argon and experimental synthetic air conditions.
Peak integrated radiance decreased by 10% due to shock curvature compared to quasi-one-dimensional results.
Observed a 40% difference in centerline axial velocity in two-dimensional modeling.
Predicted a 15% increase in radiance when accounting for two-dimensional effects.

Clarke et al. (2026) studied this question.
