Simulations were performed using semi-structured 2D meshes in FUN3D with the Spalart-Allmaras and Menter Shear Stress Transport turbulence models at a freestream Mach number of 10. The geometry includes a flat plate and four cavities with length-to-height (L/H) ratios of 0.17, 5, 15, and 30. The surface heating is found to have a strong sensitivity to freestream Reynolds numbers and some sensitivity to a change in the wall temperature. The cavity flow results are compared to Nestler et al.’s experimental data and Holifield’s CFD results. The cavities with an L/H greater than 1 presented a good match to the experimental data for both heating and pressure. The flow did not fully develop at the bottom of the L/H 0.17 gap, resulting in less accurate results close to the cavity floor.","abstract_html":"Hypersonic flow over cavities results in instabilities and discontinuities that affect the surface properties, and potentially results in surface damage.
