Abstract
Recent computational results for gas-surface reactions including atomic level simulationsof oxygen-silica recombination and microstructure level simulations of carbon-basedablative surfaces are summarized. Atomic level calculations of oxygen-silica reactions showthe main recombination mechanism to be non-activated (associated with no energy barrier).This is in contradiction to current empirical models fit to limited experimental data. Forablative porous and non-porous TPS, where complex microstructure is important, thecapability to image a real material with micron scale resolution via x-ray micro-tomography, triangulate the surface, and directly simulate the gas-surface interaction with directsimulation Monte Carlo (DSMC) is demonstrated.
