Shock-Shock Interaction Studies for Weak Incident Shocks
Abstract
The shock-shock interaction problem for weak incident waves impinging on a supersonic cone has been examined. The purpose of this study was to establish methods for predicting surface pressures since existing methods have been found inadequate for practical problems with weak blast waves. It is shown that one-dimensional theory fails when the components normal to the surface of the flight velocity and of the blast particle velocity become comparable. As a consequence, an axisymmentric two-dimensional solution method was developed using a primary wave approximation. This approach has been automated in the PRIMUS computer code. The results are presented and compared with experimental results and other theoretical predictions.
