Hypersonic flowfields are characterized by high temperature physical processes that are dormant in lower speed regimes. Recent versions of the commercial off-the-shelf flow solver STAR-CCM include models for many of the high temperature physical processes relevant to hypersonic flow. However, before the results produced from these new models can be fully trusted, it is necessary to validate the simulations against experimental data. It is also necessary to establish a set of best practices to guide the most efficient and successful use of the STAR-CCM software when simulating hypersonic flows.U The report documents a research effort with the simultaneous goals of 1 validating the capabilities of STAR-CCM and 2 establishing best practices for using STAR-CCM to simulate hypersonic flows.U Selected test case geometries include the double cone and short hollow cylinder-flare shocklaminar boundary layer interactions, the cone-flare and large hollow cylinder-flare shockturbulent boundary layer interactions, and a shockshock interaction test case. Agreement with the experiments is sufficient to validate the hypersonic capabilities in STAR-CCM . Additionally, results produced by STAR-CCM are typically equivalent to or better than those obtained using specialized solvers. Best practice recommendations are documented and can be used to guide future hypersonic flow simulations to a rapid and accurate completion.
