The 'post-correction' technique for the fitting of shocks and other boundaries

A simple technique for shock fitting, which requires no iteration, has been developed. The present technique is a simplification of a technique proposed earlier by Moretti and Abbet (1966) who succeeded in applying characteristic equations to evaluate points on rigid walls and on bow shocks. The technique is particularly efficient in the treatment of imbedded shocks, if used in conjunction with the lambda-scheme for the integration of ordinary points. The procedure has been applied to various problems of one- and two-dimensional unsteady flows and of three-dimensional steady supersonic flows.
