ON THE NUMERICAL-SOLUTION OF AN ELECTROLYTIC CONVECTIVE-DIFFUSION PROBLEM IN AN EXTERNALLY IMPOSED FORCE-FIELD

A numerical solution based on a finite-difference approximation to the nonlinear equation of an electrolytic convective diffusion problem, u sing a staggered-grid structure for the velocity and concentration fie ld, is described. The effect of externally imposed magnetic force fiel ds is manifested by additional driving terms in the ionic flux and mom entum equations. The computed overall current density/magnetic flux de nsity relationship may be represented by a simple power regression, in agreement with experimental findings.
