STRUCTURE OF TRANSPORT LINEAR-SYSTEMS IN DILUTE ISOTROPIC GAS-MIXTURES

We consider the linear systems associated with the evaluation of trans port coefficients in dilute isotropic gas mixtures and corresponding t o the first-order Enskog expansion. We obtain the structure and the ma thematical properties of these systems directly from the properties of the integral collision Boltzmann operator and the variational framewo rk used for its approximation. Using these structure properties, all t he transport coefficients can be expanded into convergent series. Thes e asymptotic expansions are particularly relevant to computational mod els in a wide range of practical applications.
