Numerical Simulation on the Shock Wave/Boundary Layer Interaction with Heating/Cooling Effect

The complicated flow conditions inner or outer of the high speed vehicle would make the shock wave boundary layer (SWBLI) much different from its standard state on an adiabatic wall. The heating and cooling effects on the SWBLI achieved by changing the wall temperature, are evaluated by the numerical simulations. It is found that the wall temperatures have significant influence on the flow patterns of SWBLI. The scale of shock induced boundary layer separation increases obviously with the rise of the wall temperature, and the separation would shrink dramatically with the decrease of the wall temperature. This could be partially explained by the variation of the momentum thickness and displacement thickness of the incoming turbulent boundary layer under different wall temperature.
