| Abstract: | Using the methods of statistical physics, the basic kinetic equation describing the dynamics of a polydisperse admixture of
solid particles in a dilute dusty-gas flow is derived. Particle rotation, inelastic collisions, and interaction with the carrier
gas are taken into account. The basic kinetic equation is used to obtain a Boltzmann-type equation for the one-particle distribution
function, for which the boundary conditions for the problem of dusty-gas flow past a body are formulated. On the basis of
the kinetic model developed, using direct statistical modeling, the flow patterns and the fields of the dispersed-phase macroparameters
in a uniform crosswise dusty-gas flow past a cylinder are obtained for various free-stream particle sizes and concentrations.
