A Numerical Procedure for Constructing Shock-Wave Envelopes around Conical Bodies using Data from Schlieren Photographs

摘要

The cross-section shape of shock-waves surrounding conical bodies can be determined by schlieren photography from measurements of the tangent planes of the shock-wave. A numerical procedure has been devised to provide a mathematical function describing the shape of the shock-wave utilising the tangent plane data and thus reducing the amount of time spent in graphical constructions as well as providing data for further analysis.
