Turbulent boundary layer thickening and separation resulting from three dimensional interaction with an oblique shock

An experimental study of the three-dimensional interaction between a shock wave and a turbulent boundary layer is presented. The shock wave produced by a dihedron is perpendicular to the wall on which the boundary layer develops itself but oblique to the general direction of the flow. The Mach number was of the order of 2.3. The boundary layer study was carried out for different angles of the dihedron nearly up to the shock wave giving rise to separation. Boundary layer development calculations are presented. The results were compared with the experiments, using the static pressure distribution measured at the wall.
