MATHEMATICAL MODEL OF TRANSFER AND DEPOSITION OF FINELY DISPERSED PARTICLES IN A TURBULENT FLOW OF EMULSIONS AND SUSPENSIONS

The problem of modeling turbulent transfer of fi nely dispersed particles in liquids has been considered. An approach is used where the transport of particles is represented in the form of a variety of the diffusion process with the coeffi cient of turbulent transfer to the wall. Differential equations of transfer are written for different cases, and a solution of the cell model is obtained for calculating the effi ciency of separation in a channel. Based on the theory of turbulent transfer of particles and of the boundary layer model, an expression has been obtained for calculating the rate of turbulent deposition of fi nely dispersed particles. The application of this expression in determining the effi ciency of physical coagulation of emulsions in different channels and on the surface of chaotic packings is shown.
