The molecular dynamics method for the interaction of the gas molecule with the solid wall together with the Monte-Carlo method for the motion of gas molecules is applied to analyze the behavior of a slightly rarefied gas between two walls. The wall consists of platinum molecules, and the gas is taken to be xenon or argon. The Couette flow and the thermal problem for which two walls have different temperature are considered. The slip and jump coefficients, tangential momentum and energy accommodation coefficients are obtained at the wall whose temperature is 300 K. The tangential momentum accommodation coefficient of argon is as low as 0.19. The distribution functions of the reflected molecules are also obtained, and it is found that the Maxwell type boundary condition describes well the distribution function of the reflected molecule.
