Abstract
In this article the flow of an electrically charged gas suspension in a channel is numerically simulated. It is assumed that the solid component of the gas suspension has a polydisperse composition. Solid component fractions may differ in particle size and density. For the velocity components of the mixture components on the channel surfaces, the Dirichlet boundary conditions were specified, thereby taking into account the wall viscosity. The dynamics of the carrier medium was described by the system of equations of a viscous compressible heat-conducting gas motion. Potentials of different signs are applied to the lateral surfaces of the channel. It was found that due to the action of an electric field, positively charged particles are deposited onto the channel wall with a negative potential. The article studies the effect of particle parameters on the deposition rate of fractions of an electrically charged solid component of the mixture.
