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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
