Macroscopic Equations for a Binary Gas Mixture

Abstract

The derivation of moment equations for the description of a flowing binary non-reacting gas mixture is presented. The equations obtained are based on a kinetic model in a relaxation form and can be regarded as the extension of the quasi-gas dynamic equations (QGD) studied before. As an example of implementation the results for the shock wave structure in an argon-xenon mixture and for the binary diffusion process of argon and helium are presented in comparison with the DSMC results.
