Abstract
Supersonic shock wave/turbulent boundary layer interactions were simulated by employing three popular engineering turbulence models, namely Spalart-Allmaras(SA), k- , shear stress transport(SST) over a 24ºcompression ramp at Mach 2.84 and a 11º×11º double-sharp fin plates at Mach 2.91. Comparisons of pressure distributions and skin friction coefficient on the wall with experimental results show that, for the compression ramp, SA model is superior to other models for calculating pressure distribution, the friction coefficient given by SST model is closest to the experimental results. For double fin plates, the pressure distributions of three turbulence models are all close to the experimental results at the centerline, except peaking value, SST model is more accurate for skin friction distributions than SA model and K- model. In summary, SST model is more accurate for calculating wall pressure and skin friction coefficient distributions, improvements must be made for simulating supersonic shock wave/turbulent boundary layer interaction to the three turbulence models.
