The characteristics of vibrational and rotational temperatures distributions of N2, O2, and NO along a stagnation streamline were investigated numerically in detail by the extended merged shock-layer theory for reentry flows. The calculation was based upon an 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 intensely appeared in the entire shock layer, and that the distributions of vibrational and rotational temperatures for each molecule were quite different from each other, and also from that of translational temperature.
