摘要：
In the paper, we numerically simulated the dynamics of a polydisperse gas suspension in a channel. The dynamics of the carrier medium were described by the two-dimensional Navier-Stokes equation for a compressible heat-conducting gas. The mathematical model assumed a difference in gas suspension fractions based on the linear size of dispersed inclusions and the density of the material. The system of mathematical equations was integrated by the finite-difference method. To overcome numerical oscillations, a nonlinear correction scheme was applied to the grid function. The influence of the aerodynamic drag force, the dynamic Archimedes force and the force of added masses on the dynamics of dispersed inclusions in the gas was taken into account. It was assumed that a dusty medium moves in the channel, and droplet fractions are blown through the side surface. The influence of the dispersity of droplet inclusions on the spatial distribution of droplet fractions, as well as the influence of the injection of droplet fractions on the distribution of the dust fraction of a gas suspension, was revealed.
