Abstract

The Bhatnagar-Gross-Krook (B.G.K.) model for a binary gas mixture contains three unknown parameters. For a particular application these parameters can be found by comparison of the B.G.K. solution with a known solution of the Boltzmann equation for the problem under consideration. In this paper the hydrodynamic solution, obtained according to the Chapman-Enskog procedure, is used as such. Relations are derived between the unknown parameters of the B.G.K. model and the transport coefficients following from the hydrodynamic solution.
