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

THE MODELS OF CALCULATION OF TURBULENT BOUNDARY LAYER AT PERMEABLE SURFACE
Description
In the article we have considered the mathematical models of turbulent boundary layer corresponding with condensation and evaporation. The expressions for accounting that effect have been derived. We have also compared them with the known experimental data
