Abstract
We present a detailed statistical description of turbulence in the high-fidelity Large Eddy Simulation (LES) of hypersonic shock-and-turbulent boundary layer interactions with strong separation. Our high-fidelity LES method uses a 4th-order, bandwidth-optimized Weighted Essentially Non-Oscillatory (WENO) scheme combined with a robust shock-capturing method and dynamic mixed model formulations for the closure of subgrid scale terms. Our mixed models, which contain a scale-similar term in addition to the purely dissipative one, are shown to accurately and significantly improve separation prediction compared to purely dissipative closures, such as the dynamic eddy viscosity formulation.
