Abstract

Using the theory of turbulent migration of particles and boundary layer models, expressions for calculation of particle transport coefficients and of mass transfer within the continuous phase are obtained. Various cases of turbulent direct flow of particles through the carrier turbulent medium are considered: smooth and rough channel; channel filled with fine random packing and apparatuses with mechanical mixing. Examples of calculation of mass transfer from droplets and solid particles are included and their agreement with experimental data of other authors is demonstrated.
