MATHEMATICAL MODELS AND CALCULATION OF THE HYDRODYNAMIC CHARACTERISTICS OF A BOUNDARY LAYER
Description
The processes of momentum transfer in laminar and turbulent boundary layers are considered. We have obtained the proprietary models for calculation of shear stresses, turbulent viscosity, friction factors, boundary layer thickness and momentum transfer coefficients in boundary layers under different conditions of motion of media. The examples of the calculation of the above characteristics and their agreement with known experimental data are shown. The obtained equations and the methods of calculation of the boundary layer characteristics can be used for calculations of industrial heat and mass transfer apparatuses of various designs as well as of some other types of equipment

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
