Historically, efforts have been made to model the interaction between ablative material and hypersonic flow through copling strategies. In this paper, a solver that uses a unified approach is considered to study for the gas surface interactions. The solver uses Volume Averaged Navier-Stokes (VANS) equations to solve for both porous material and hypersonic flow at the same time. The capability of the solver was assessed in the past by simulating the high speed flow in supersonic and hypersonic coditions through porous materail. In the present work, high speed flow simuations accounting the thermal non-equilibrium are run. More specifically, two-temperature model proposed by Park[1] is implemented, where non-equilibrium effects at the gas-surface interface are studied. Reference 1.
