Three single equation turbulence models were applied to a test case of a Mach 9 flow over a 38 deg ramp. None of the models have been optimized to high-speed flows. Results indicate that the Rt closure outperforms both the Spalart-Allmaras and Menter’s models in predicting this flow. Since the Rt model’s formulation is also topography-parameter-free, it seems to be the best choice for use in hypersonic heat transfer prediction within the single equation closure family.
