Boundary slip phenomena in a binary gas mixture

摘要: The slip phenomena in gas mixtures are of fundamental significance the specification boundary conditions for flows regime. In a recent paper, new explicit results coefficients appropriate to binary were reported. present work being reported extends previous higher level accuracy by involving order Chapman-Enskog expansion. particular, expressions presented which applicable arbitrary models intermolecular interaction. Limiting given (for simple gas) and theory is discussed. Numerical calculations different using first second approximations rigid sphere Lennard-Jones (12-6) potential have been carried out. thermal creep diffusion found be sensitive approximation model used. A comparison with some our previously obtained experimental data transpiration effect has also out shows excellent agreement between experiments confirms theory.
