Abstract

A kinetic model is proposed for the description of a finely dispersed gas suspension. The influence of the solid particles on the carrier gas is taken into account by introducing in the kinetic equation a collision operator of special form. A modification of the Chapman—Enskog method is developed to solve the obtained kinetic equation, this making it possible to find a solution without assuming that the solid particles have little influence on the gas. As a result, closed expressions are obtained for the effective transport coefficients of such gas suspensions. The influence of an admixture of a charge aerosol on the transport properties of an ionized gas is investigated. The obtained results are used to find the fields of the gas-dynamic parameters in the case of supersonic flow of a gas with particles over a blunt body.
