SIMILARITY RELATIONS FOR 3-DIMENSIONAL VISCOUS FLOWS IN CHEMICAL DISEQUILIBRIUM

Three-dimensional hypersonic flow of viscous gas in chemical disequili brium around blunt bodies is investigated. A method is proposed for so lving such three-dimensional problems by means of two-dimensional solu tions applicable with arbitrary Reynolds numbers for real gas properti es. The method is based on similarity relations expressing the heat fl ux, friction, and concentration of the components at the surface of an axisymmetric body. The accuracy of the similarity relations is estima ted by finite-difference calculations of the three-dimensional equatio ns of the Viscous shock layer for bodies of various shapes entering th e Earth's atmosphere along planned trajectories. Various models of cat alytic surface activity are considered.
