The characteristics of reflected gas molecules at H_2O adsorbed surfaces are investigated by applying the molecular dynamics method for the interaction of gas molecules with the adsorbed surface together with the DSMC method for the motion of molecules. In this study, the flow problem between two walls, i.e., the Couette flow, is considered. The gas is taken to be argon and the wall surface consists of platinum molecules. The tangential momentum accommodation coefficient of 0.42 is obtained at the wall whose temperature is 300K. The flow velocity between two walls and the distribution functions of the reflected molecules are also obtained. It is found that the Maxwell-type boundary condition describes well the distribution function of the reflected molecules.
