The effects of several catalytic boundary conditions implemented in a hypersonic flow solver are analyzed for a sphere/cone geometry representative of a re-entry body. The three-dimensional Navier-Stokes equations solver uses a five-chemical-species model. The simulated surface is silica, representative of coatings for thermal protection systems. The range of wall temperatures explored is 300-1500 K, and fully catalytic, local-equilibrium, noncatalytic, and finite-rate catalysis boundary conditions are applied and discussed. For finite-rate catalysis a recent model for simultaneous recombination of O and N atoms, including NO formation, is used. A comparison of all the boundary conditions implemented with results from fit-based finite-rate catalysis boundary conditions is made at surface temperatures of 1200 and 1500 K. Numerical simulations results are compared and discussed, and conclusions about which boundary conditions are best in each case are drawn.
