An apparatus and method of stabilizing unstable shock waves on the surface of a body induce shock waves to form prematurely at a particular location on a surface of the body and fix that location such that shock waves will form consistently and persistently at that location on the surface of the body. Boundary layer flow separates from the surface of the body at that location and can be prevented from reattaching to the surface. Shock wave oscillations due to interactions with the separated boundary layer flow are prevented, thereby minimizing vibrations induced in the body. The apparatus has a flow accelerating surface and a discontinuity in the accelerating surface. The accelerating surface causes local fluid flow over the surface of the body to accelerate and prematurely and consistently form a shock wave at the point where the discontinuity is located. The discontinuity causes separation of the boundary layer flow from the body surface and fixes the location where the boundary layer flow separation occurs. The method prematurely forms a shock wave at a set location on the surface of the body and fixes both the formation of shock waves to the set location and the separation point where the boundary layer detaches from the surface of the body.
