Boundary slip phenomena in a binary gas mixture (Q1596393)

The present paper extends some previous results to a higher level of accuracy by involving a higher-order Chapman-Enskog expansion. In particular, new expressions for the slip coefficients are presented which are applicable to arbitrary models of intermolecular interaction. Limiting expressions for slip coefficients are given (for a simple gas), and the accuracy of the theory is discussed. Numerical calculations of slip coefficients are given for different binary gas mixtures.
