N2 - This work assesses the nonequilibrium flow prediction capabilities of multi-temperature dissociation models used in computational fluid dynamics. Three different hypersonic flow attributes; shock standoff distance, the vibrational temperature behind a strong shock, and surface heat flux and pressure distribution were investigated for the Park, Kuznetsov, and Macheret-Fridman dissociation models. The flow features were discussed based on various characteristics of dissociation in vibrational nonequilibrium represented by the models considered in this study.
