A full Navier-Stokes procedure

coupling with a Baldwin/Lomax turbulence model

is used to study the normal shock wave/turbulent boundary layer interaction with passive cavity.In addition

the ventilation velocity profile on the porous plate is calculated by a empirical model formulated from experiments.The total pressure and total temperature boundary conditions for inflow are given due to the existancc of sonic section in the channel flow and the static pressure boundary condition for out flow is given as well.The comparison between numerical and experimental results shows that the presented procedure can predict the shape of the shock

the mach number in front of the shock

the pressure ratio on the wall and position of the shock quite well.
