Abstract
Within the framework of the kinetic approach to the description of the motion of a gas suspension estimates are obtained for the flow parameters on the basis of which it appears possible to apply the Chapman-Enskog method to an equation of the Boltzmann type written for the admixture phase. In this case the carrier gas can be described within the framework of the ideal gas model with allowance for interaction with the particles of the admixture phase. As the equation of state for the particle “gas” an equation of the van der Waals type is employed. This makes it possible to take regions of high particle concentration into account more correctly than within the framework of the ideal gas model. The problem of supersonic dusty gas flow over a sphere is solved on the basis of this approach.
