Abstract

A conservative cut-cell immersed boundary (IB) method including gas-surface interactions (GSI) for the simulation of atmospheric entry flows under thermochemical nonequilibrium (TCNE) conditions is presented. The performance
of the method is demonstrated for three test cases: a compression ramp, a cylinder, and a plasma wind tunnel ablator sample. The computational predictions are in excellent agreement with reference simulations and experimental data for translational and vibrational temperature variations in the flow field, pressure and heat flux distributions over the geometries, and the mass blowing rates over a surface undergoing ablation.
