Calculation of the Boundary Layer of a Two-Phase Medium

Results are given of the calculations of the turbulent boundary layer of a two-phase mixture consisting of a gas and spherical particles ∼10–6 m in size. The problem formulation is presented, and the concentration of particles on the wall and the heat flux to the wall are determined. The two-phase mixture is treated as Newtonian liquid, and the gas and solid particles which form this mixture are calculated as continuous flows. The calculation of a two-phase flow in the boundary layer is performed with due regard for the effect of the concentration of solid particles on the viscosity and thermal conductivity of a binary mixture in the presence of the forces of interfacial interaction.
