The Application of Pulsed Current Electrolysis to a Rotating‐Disk Electrode System: I . Mass Transfer

Abstract

A numerical solution was obtained for mass transfer to a rotating‐disk electrode under pulsed current conditions. Good agreement was reached on the calculation of rate of mass transfer between the numerical solution and the solution by Cheh from a simplified diffusion model. The concept of a pulsating diffusion layer was introduced and it was shown that the thickness of the pulsating diffusion layer was a function of the pulsed current characteristics as well as the Reynolds and Schmidt numbers of the system. Experimental verification of the theoretical results was obtained by using a model ferri‐ferrocyanide electrolysis.
