Kinetic model of a collisional admixture in dusty gas and its application to calculating flow past bodies (Q1592043)

Using the methods of statistical physics, the authors derive the basic kinetic equation describing the dynamics of a polydisperse admixture of solid particles in dilute dusty gas flow. Particle rotation, inelastic collisions and interaction with the carrier gas are taken into account. The basic kinetic equation is used to derive a Boltzmann-type equation for one-particle distribution function, for which the boundary conditions are formulated in the case of dusty gas flow past a body. For various free-stream particle sizes and concentrations, the authors obtain flow patterns and dispersed-phase macroparameters in a uniform cross-flow of dusty gas past a cylinder.
