Density Effects on the Transport Coefficients of Gaseous Mixtures

Abstract
A modified Boltzmann equation for mixtures, which includes the effects of collisional transfer and three‐particle collisions, is presented. This equation is then solved by a perturbation expansion. General expressions for the fluxes are derived, and the transport coefficients are expressed in terms of the perturbation coefficients. Finally, the various integrals encountered in the development are evaluated numerically.
