Abstract

A theoretical analysis of the flow pattern at a solid surface in three-dimensional supersonic flow is presented. The purpose of the study is to develop the additional information necessary to overcome the nonuniqueness associated with the body tangency condition in three dimensions. The analysis is based on the fact that three-dimensional waves propagate locally exactly as they do in axisymmetric flow when viewed in the osculating plane to streamline. The supersonic flow over an infinite swept corner is examined by both the classical solution and the three-dimensional solution in the osculating plane; the results are shown to be identical. A simple numerical algorithm is proposed which accounts for the three wave surfaces that interact at a solid boundary.
