The thermal problem of a rarefied argon (Ar) gas between two parallel walls is considered to investigate the characteristics of the reflected gas molecule at a platinum (Pt) wall surface which physically adsorbs water (H 2 O) molecules. The analysis is based on the molecular dynamics (MD) method for the interaction of gas molecules with the water adsorbed wall surface together with the direct simulation Monte-Carlo (DSMC) method for the motion of gas molecule. The accommodation coefficients of

It is found that the accommodation coefficients for the water adsorbed surface decrease with increasing the adsorption rate.
