CALCULATION OF CONVECTIVE TRANSFER
OF WATER-SOLUBLE COMPOUNDS WITH
ACCOUNT FOR SORPTION KINETICS
G. P. Brovka

UDC 519.6

An asymptotic solution is obtained for the equation 
of convective diffusion of water-soluble compounds with account for 
sorption kinetics with the linear isotherm of the sorption of them 
by a solid disperse phase. It is shown that the hydrodispersion is 
proportional to the squared linear velocity of a liquid flow and is 
inversely proportional to the mass-transfer coefficient which determines 
the rate of establiment of the sorption equilibrium.
