Abstract

The large-eddy simulation (LES) of a hypersonic flow passing a single-fin at Mach 5 and Re∞=3.7×107/m was conducted and the three-dimensional (3D) shock wave/turbulent boundary layer interaction (SWTBLI) was studied in the present paper. This is probably a first reported LES of this kind of flows. The newly developed seventh order low-dissipation monotonicity-preserving scheme is used to solver the Euler fluxes and the dynamic Smagorinsky subgrid model is used to take account of the subgrid stress and heat flux. The shock system, flow separation structure, and turbulence characteristic are investigated by analyzing the LES data. The turbulence in the 3D SWTBLI is found to be dominated by small-scale wall turbulence, large-scale free shear turbulence, as well as the corner vortex in different regions. In the reverse flow, the streamwise elongated coherent structures are regenerated beneath the main separation vortex, almost immediately after the flow reattachment.
