EFFECT OF CONTACT SURFACE BLUNTNESS ON MASSIVE BLOWING FROM A WEDGE IN HYPERSONIC FLOW.
Abstract
An inviscid, compressible analysis is given for massive blowing from the porous surface of a wedge or flat plate in a hypersonic free stream. An inverse procedure is used whereby the specified geometry of the contact surface is that of a blunted wedge. The resulting mathematical formulation which uses natural coordinates and the Fourier cosine transform, is notable for its simplicity. Attention is focused on the induced pressure field in the injected gas due to the contact surface's bluntness. Detailed results, however, are given only for the flat plate. For this case, appreciable induced tangential and normal pressure gradients occur in the injected gas flow near the leading edge. An interesting result is that the pressure and velocity distribution on the plate is given by a single universal curve, when distance along the plate is properly scaled. (Author)
