INVESTIGATION OF CHEMICAL NONEQUILIBRIUM EFFECTS IN VISCOUS SHOCK LAYERS

Abstract

The shock layer about a blunt body in a hyper sonic flow field is studied considering both viscous and chemical nonequilibrium effects. An order of magnitude study is conducted to predict flight regimes for chemical equilibrium and for frozen flow. Conservation equations are formulated for the viscous, reacting flow in the shock layer about a sphere using a seven species, six reaction al model. A numerical method for solution of these equations is developed and the results of solution attempts discussed.
