We present a study on the effects of passive control on interaction of an oblique shock wave with a turbulent boundary layer. The experiments were carried out in a 10×8cm² supersonic wind tunnel at a free stream Mach number of 1.97. The incident oblique shock wave impinging on the porous wall of the floor of the test section was generated by a wedge mounted at the center of the test section. The effects of the passive control were studied by varying the porosity of the porous wall from 0% (solid) to 20% at various shock wave angles. Surface static pressure measurements and Schlieren observations as well as measurements of the blowing/suction velocity at the porous wall were made. It was found that for strong shock the reflected shock moves to the starting point of the porous region and the surface pressure increases linearly from this point. Furthermore, for a 5% porous wall the normal velocity was of the Darcy type and was about 30% of the main flow velocity.
