Ag. Laptev et al., MATHEMATICAL-MODELING OF MASS-TRANSFER IN THE INTERMIXING OF 2-PHASE MEDIA, Russian journal of applied chemistry, 66(3), 1993, pp. 437-442
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
.
