The present numerical investigation addresses the hypersonic flow over the double-wedge using various gas models exposed to low and high enthalpy free stream conditions. The solver ’hyperKineticFoam’ is developed in the finite volume framework, OpenFOAM© environment, capable of simulating the high-temperature effects in hypersonic flows representing vibrational and chemical non-equilibrium. This solver utilized in the present numerical investigation to address the impact of different gas models, i.e. thermally perfect gas (TPG) and thermal non-equilibrium with frozen chemistry (TNEQ) on the double-wedge configuration by exposing it to the pure Nitrogen with two different free stream conditions. One of the free stream conditions corresponds to the low enthalpy with 2MJ/kg at the inlet, while the high enthalpy represents 8MJ/kg. The preliminary results obtained by comparing the present investigation’s data against the experimental results indicate negligible effects of the different gas models on the numerical solution for the low enthalpy case. At the same time, there are minute differences concerning the high enthalpy free stream conditions.
