As part of the AVT-352 on hypersonic turbulence, a code-to-code comparison has been initiated to evaluate the status of RANS modeling for such flows. To this end, two sharp cone-flare geometries, experimentally studied at CUBRC have been selected for study. Each geometry has been run at various conditions enabling a larger sampling for the various participating CFD codes and turbulence models. The nature of the physics found in cone-flare geometries are known to be extremely challenging for RANS CFD codes. This paper presents an initial status on this endeavor, describing the setups, conditions and general simulating strategies. Initial simulations confirm the typical overpredictions of pressure and heat flux along the wall after the region of separation.
