THEORY OF NONSTATIONARY MASS-TRANSFER IN A TURBULENT ELECTROLYTE FLOW

One of the possible methods for calculating concentration profiles and the rates of interphase mass transfer under the conditions of turbulent flow of the electrolyte solution is described. In the case of a surface which is equiaccessible in the diffusion sense, as well as in the case of a channel of constant cross section sufficiently far from the diffusional entrance region, i. e. , in systems in which the concentration profile does not vary significantly along the mass-transfer surface, the equation of the local concentration of the transferred component is presented. An abrupt stepwise concentration pulse on a wall is considered and the theoretical analysis of turbulent mass transfer is furnished.
