| Description |
A novel yet efficient method for the computation of simplified tertiary current density and surface concentration
distributions in electrochemical processes is presented. The method is rooted in the important physiochemical
property that the activation potential is constant and uniform for given electrode material during the electrolysis.
The technique is attractive because it involves a single iterative procedure against the conventional doubly iterative
procedure. The initial assumption of current distribution along the electrode is also not necessary, as it involves only
an assumption of a suitable power series to solve steady state laminar convective diffusion. Accordingly the method
is relevant only for electrodes of constant activation polarization, but this holds good for situations where the
electrode configurations are such that the primary current density distribution is almost uniform and for situations
where the Wagner number is high. To illustrate the utility of the technique the procedure is applied to some realistic
problems encountered in electrochemical engineering such as the current distribution either in plane-parallel plate
electrode with electrolyte flowing between them or a moving electrode with the electrolyte stationary.
