Convective-Diffusion Model of Transfer of a Sedimenting Low-Concentration Polydisperse Suspension of Stokesian Particles in a Plane Channel. Part I

Abstract

With the analytical expression for the local particle size distribution function in the case of flow of a low-concentration polydisperse suspension whose dispersed phase moves in a turbulent regime simulated by the ideal-displacement model, the authors have quantitatively assessed the regularities of formation of the fields of mass concentration in the flow over the cross section and along the length of the channel, and also of thicknesses of sediments on the upper and lower "wetted" surfaces and their particle size distribution as functions of the intensity of mixing and the particle size distribution of the suspension.
