Abstract

In this paper we consider the problem of the concentration jump of a vapour in the vicinity of a plane wall, which consists of the condensed phase of the vapour, in a rarefied gas mixture of that vapour (A) and another ‘inert’ gas (B). The general formulation of the problem of determining the concentration-jump coefficient CdA is given. In the Knudsen layer the simplest model of Boley-Yip theory is used to simplify the Boltzmann equations for the binary gas mixture. The numerical calculation of the concentration jump coefficient CdA for various values of evaporation coefficient αA is illustrated for the case of nB [Gt ] nA for which experimental data are available.
