MATHEMATICAL-MODELING OF MASS-TRANSFER IN THE INTERMIXING OF 2-PHASE MEDIA

A mathematical description is obtained for mass transfer proceeding in a continuous phase when mixing two reciprocally insoluble liquids (ex traction process) and suspended solid particles (dissolution process) based on the given law of extinguishing turbulent pulsations in the bo undary layer. The main parameters of the model, i.e., dynamic velocity and the dimensionless thickness of the boundary layer, are determined from the equation of impulse and energy dissipation balance. The resu lts of mass transfer coefficient calculations are shown to be consiste nt with known experimental data. Intermixing of liquid media containin g disperse phase elements in the form of drops or solid particles is w idely used in different industries in order to intensify mass transfer .
