Computation of hypersonic flows with finite catalytic walls

A computational study has been performed to explore the effects of finite catalytic walls on hypersonic flows. Boundary conditions for noncatalytic, fully catalytic, and finite catalytic walls have been incorporated into an upwind parabolized Navier-Stokes code. Nonequilibrium laminar airflows over sharp cones at 0 and 10 deg angle of attack were computed and the results are compared with previous results wherever possible. 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 temperature assumption. Detailed effects on specie concentrations, temperature, and heat transfer are presented.
