Deriving Features of Reacting Hypersonic Flows from Gradients at Curved Shocks

Abstract

The shock jump relations for gradients of flow variables are presented in the case of a uniform steady free stream with a curved shock that may trigger endothermic or exothermic chemical reaction. The rich information that can be obtained from these is used in order to derive field information for flow variables as well as details about the sonic line. This presentation collects, reviews and extends work that has been published previously in various places. Comparisons with experiment and with numerical computations are given in some cases. The gradient jump relations are Likely to be useful for higher-order numerical schemes that use shock fitting.
