COMMENTS ON IONIC MASS TRANSFER RATES IN ELECTRODIALYSIS

Abstract

Kitamoto and Takashima^{1, 2)} have recently reported experimental data and some numerical computations for limiting current density in an electrodialysis-type system, under laminar as well as turbulent flow conditions. The purpose of this note is, first, to point out that the authors have not observed that their data for laminar flow is in good agreement with a previously published analytical theory³⁾, reference to which is made in Ref. 2; second, to question their turbulent flow model for the correlation between concentration and electric field fluctuations; and last to raise some points concerning both the laminar and turbulent numerical calculations.
