Calculation of mean current densities in a two rotating disc electrodes system

Abstract

A theoretical relationship for mass transfer in the laminar flow region of streaming in a rotating electrotyser was derived by the method of similarity of the diffusion layer t'or electrodes placed sufficiently far from the rotation axis. The obtained relationship was compared with the known equations valid for systems with axial symmetry. The mean current densities were found from the numerical solution of the convective diffusion equation by the finite-element method and were compared with experimental results.
