Abstract
The characteristics of vibrational and rotational temperatures of N2, O2, and NO were investigated numerically by the extended merged shock-layer theory for low-density hypersonic flow. The calculation was based upon a 8-temperature and 11-chemical species model. The analysis assumed a continuum approach and the system of governing equations constituted a two-point boundary value problem that was solved using the SAR method. It was found that the effects of thermally and chemically nonequilibrium phenomena appeared in the entire shock layer, and that the distributions of vibrational and rotational temperatures for each molecule were quite different from each other.
