Wall-modeled large eddy simulation of high speed flow over a blunt ogive cone*

The state-of-the-art in wall-modeled large eddy simulation (WMLES) has made significant advancements towards predicting the flow properties of canonical zero pressure gradient cases at high-speed conditions. Recent wall-models are capable of predicting wall quantities accurately to within 10% of direct numerical simulations (DNS) and hence hold promise towards application to more challenging test cases such as non-zero pressure gradients and cold wall conditions. In this work, we perform WMLES for high-speed flow over a blunt ogive cone with cold walls, using geometry and flow conditions from Morreale et al. (AIAA SCITECH 2023 Forum, 2023) with the objective of testing the applicability of these wall-models and to explore possibilities of further improvements in wall-modeling for more realistic cases.
