Abstract	Time-resolved laser-induced incandescence demands precise knowledge of the thermal accommodation coefficient, but little is known about the gas-surface scattering physics that underlies this parameter. This paper presents a molecular dynamics simulation that shows how the thermal accommodation coefficient is influenced by the gas molecular mass and gas temperature. The molecular dynamics results also define scattering kernels that can be used as boundary conditions in Direct Simulation Monte Carlo simulations of heat and momentum transfer between soot aggregates and surrounding gas molecules.
