A two-dimensional blunt body was submerged in a compressible turbulent boundary layer and the surface pressure was measured. It was found the fore-body drag was reduced due to the velocity defect in the boundary layer and the associated re-circulation behind an oblique shock wave. A small two-dimensional shock generator ahead of the blunt body further reduced the drag of the blunt body.
