Calculation of Compressible Flows with local regions of supersonic velocity

Gothert, B., Kawalki, K. H.

A method of calculating the approximate velocity field for compressible flows with local regions of supersonic velocity has been presented. Starting from the flow at a large distance from the profile determined according to Prandtl's rule, this outer flow was continued to the sonic velocity boundary by means of a numerical method; the method of characteristics of Prandtl-Busemann was applied for continuation beyond that boundary. These calculations result finally in the contour of the profile in the region of supersonic velocity.
