TURBULENT TRANSFER EFFECTS OF THE FINE PARTICLES IN THE LIQUID PHASE OF DYNAMIC SEPARATORS
Description
The turbulent movement of the liquid with dispersed phase in the channels of thin layer clarifiers and hydrocyclones is reviewed. The evaluation of the dimensions of the particles, which are taken by the turbulent pulsation is performed. The turbulent sedimentation of the fine phase is researched as a type of a process of diffusion. Using the equations from the theory of mass transfer and the edge of the turbulent level, the coefficients of the speed of the transfer of the particles are acquired. The results of the calculations, covering the effectiveness of the turbulent separation are provided, with the use of the models of perfect mixing and displacement
