Abstract

A kinetic theory for a mixture of ν-polyatomic gases of perfectly rough, perfectly elastic, and rigid spherical molecules is developed. A macroscopic state of the mixture is characterized by 16ν+1 fields of partial densities, partial velocities, partial pressure tensors, partial translational heat fluxes, partial rotational heat fluxes, and temperature of the mixture. The generalized laws of Fick, Fourier, and Navier–Stokes are obtained from an iteration method akin to the Maxwellian procedure. As an application, the transport coefficients for binary mixtures of CH4–CF4, CH4–CD4, and CD4–CF4 are determined.
