Abstract
The gas-wall interaction is investigated for the Couette flow and the thermal problem between two walls whose temperature are different each other. The wall consists of platinum molecules and has grooves in molecular scale. The method of analysis is based on the molecular dynamics as well as DSMC method. The gas is taken to be argon. The slip and jump coefficients, tangential momentum and energy accommodation coefficients are obtained at the grooved wall surface whose temperature is 300K.
