MATHEMATICAL MODELING OF MASS TRANSFER IN LAMINAR MOTION OF A DROPLET IN A LIQUID MEDIUM

Consideration is given to mathematical modeling of the process of nonstationary liquid–liquid extraction in apparatuses with free motion of a dispersed phase. Solutions of nonstationary equations of transfer of momentum and mass in the boundary layer on the droplet and inside the droplet near the phase boundary are given. Equations for calculation of the coeffi cients of mass transfer and concentration of the extracted component are obtained. A comparison is made of the calculated data and experimental results in extracting various liquid mixtures.
