Abstract : The boundary-layer flow is forced to separate from the wall when a downstream compressive disturbance of sufficient magnitude is encountered. The correct asymptotic mathematical structure for such a viscous-inviscid interacting flow has been developed by Stewartson and Williams in their paper on self-induced separation. A numerical solution of these asymptotic equations of motion is presented here for the case of separation produced in supersonic flow past a compression ramp. The flow through separation ahead of the corner agrees with the Stewartson and Williams solution, but the reattachment of the separated flow onto the ramp is of different nature than the downstream flow in their case.
