Effect of rotational nonequilibrium behind a normal shock wave in oxygen and nitrogen flow
Résumé
In this study, the effect of rotational nonequilibrium on the macroscopic parameters of the flow behind a normal shock wave in oxygen and nitrogen gas flow has been examined. Comparison between three chemical kinetic models including Park89, Park93, and Dunn-Kang was used to describe the chemical nonequilibrium. The obtained results show the significant effect of the rotational nonequilibrium on the relaxation zone and also on the translational and vibrational temperatures and were found to be in a good agreement with the experimental data particularly when the Park89 model was used.
