摘要：
A numerical computation of an oblique shock wave incident on a turbulent boundary layer was performed for free stream flow of air at M-infinity = 2.0 and Re-1= 10.5x10(6) m(-1). The oblique shock wave was generated from a 8 degrees wedge. Reynolds averaged Navier-Stokes (RANS) simulation with k-omega SST turbulence model was first utilized for two dimensional (2D) steady case. The results were compared with the experiment at the same flow conditions. Further, to capture the unsteadiness, a 2D Large Eddy Simulation (LES) with sub-grid scale model WMLES was performed which showed the unsteady effects. The frequency of the shock oscillation was computed and was found to be comparable with that of experimental measurement.
