A Rankine-Hugoniot Emulating (Density vs. Velocity) Relationship for CFD Usage Within an Inviscid Shock Wave

Abstract

To enable the Full Potential Equation method of computing transonic inviscid flows to accurately predict the conditions at exit from a shock wave - a desirable aim which the method fails to achieve to a greater or lesser extent - an improved relationship has been derived between the density (p) and velocity (q) inside an inviscid shock wave. This relationship replaces the conventional isentropic, isenergic relationship normally applied there. The shock exit conditions thereby obtained are the correct Rankine-Hugoniot values, for all shock inlet Mach numbers.
