A computational study has been performed to examine the effects of catalytic walls on stagnation region heat transfer. Boundary Conditions for none, finite, and fully catalytic walls have been incorporated into a Multi-Block Compressible Navier-Stokes code. Both chemical and thermal non-equilibrium effects were included. Flows over a blunt body model were simulated by varying surface catalytic recombination rates. A full range of catalycities was explored in the context of a constant wall temperature assumption. Detailed information on species concentrations, temperature, and surface heat flux are presented. Comparison with the available flight data of surface heat flux is also made.
