COMPUTATION OF HYPERSONIC FLOWS WITH FINITE CATALYTIC WALLS

A computational study has been performed to explore the effects of fin ite catalytic walls on hypersonic flows. Boundary conditions for nonca talytic, fully catalytic, and finite catalytic walls have been incorpo rated into an upwind parabolized Navier-Stokes code. Nonequilibrium la minar airflows over sharp cones at 0 and 10 deg angle of attach were c omputed and the results are compared with previous results wherever po ssible. A study of finite catalytic cases was performed using varying recombination rates, Full ranges of catalycities were explored in the context of the surface energy balance as well as a constant wall tempe rature assumption, Detailed effects on specie concentrations, temperat ure, and heat transfer are presented.
