Nonequilibrium Stagnation Point Boundary Layers with Arbitrary Surface Catalycity

摘要: An approximate theory of nonequilibrium stagnation point boundary layer flow on highly cooled blunt bodies at hypersonic flight speeds, including a finite atom recombination rate the surface, is presented. The analysis based simplified nonlinear representation reaction distribution across which derived from fact that near wall dominates behavior when cooled. Closed-form solutions for conditions gas/solid interface, such as concentration and heat transfer, are obtained in terms universal function single, composite Damkohler number. This number represents combined effects homogeneous heterogeneous over wide range various thermochemical parameters involved. found to be good agreement with numerical results reported by Fay Riddell.
