Abstract

We consider a Couette flow of a rarefied Ar gas with heat transfer between two walls and investigate the scattering behavior of gas molecules reflected either at a clean Pt surface or at a surface contaminated with adsorbates. The reflection of gas molecules on the lower wall is simulated by Molecular Dynamics (MD) method to obtain accommodation coefficients and velocity distribution functions of gas molecules. We also investigate the validity of reflection model of gas molecules on the wall by comparing with the MD results. In addition, we discuss thermal and flow properties between two walls from the obtained flow velocity and temperature distributions.
