Rational GAO-YONG compressible turbulence equations were applied to simulate numerically the flat plate shock wave/turbulent boundary layer interactions. The equations were solved using the semi-implicit method for pressure-linked equations (SIMPLE) algorithm. The discretization of convection and diffusion terms were respectively adopted quadratic upwind interpolation of convective kinematics(QUICK) scheme with third-order precision and center difference (CD) scheme.The calculational results predict well the flow characteristics of turbulent boundary layer separation induced by incident shock wave: a separation shock followed by expansion fan around separation bubble and shock in reattachment point.The computational results of the time-averaged parameters, such as the velocity profiles along the ��x��-coordinate, pressure along the wall surface and skin-friction coefficient along the wall were compared with the experimental results. It is shown that when the GAO-YONG compressible turbulence equations are applied to the shock wave/turbulent boundary layer interacting cases, the basic feature and details of shock flows can be well simulated.
