KINETIC-THEORY FOR MIXTURES OF POLYATOMIC GASES OF ROUGH SPHERICAL MOLECULES

A kinetic theory for a mixture of v-polyatomic gases of perfectly rough, perfectly elastic, and rigid spherical molecules is developed. A macroscopic state of the mixture is characterized by 16v + 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-CD 4, and CD4-CF4 are determined. © 1990 American Institute of Physics.
