KINETIC-THEORY OF DILUTE GAS-MIXTURES WITH INDEPENDENT INTERNAL ENERGY MODES NEAR-EQUILIBRIUM

We extend the kinetic theory of dilute polyatomic gas mixtures to the case where the particles have various internal energy modes. The prese nt theory is valid when the internal energy modes are mechanically ind ependent and when the various degrees of freedom of the molecules are at zeroth order equilibrium. In this case, we derive new transport lin ear systems with which to evaluate all the transport coefficients of t he mixture. These linear systems are given explicitly in terms of vari ous collision integrals and provide expressions for the volume viscosi ty, the shear viscosity, the species diffusion coefficients, the therm al diffusion coefficients, and the partial thermal conductivity.
