In this paper, the SU2-NEMO CFD solver is used to simulate conditions in the HyMETS arc jet test facility in order to test models of gas-surface interaction for catalytic heating augmentation in nonequilibrium flows. Simulation predictions of surface heat flux and pressure on a calorimeter probe are verified and validated against numerical results and experimental data. A sensitivity analysis with respect to surface chemistry modeling parameters is then conducted focusing on the impact of catalytic efficiency on surface heating rates.
