Abstract
On the basis of copper winning in a sulphuric acid medium this paper presents an original calculation method for the design of a continuous parallel plate electrolytic cell consisting of three zones: a turbulent bulk in which convection and migration take place and two thin boundary layers at each electrode where diffusion and migration phenomena are taken into account. Current densities and species concentration profiles may be deduced from this model with the aid of mass transfer and electrochemical kinetic data. For conditions corresponding to industrial applications it can be shown that longitudinal migration in the bulk can be neglected. The validity of the model is successfully proved; in particular, results accounting for the effect of ionic migration on the limiting current density are in a good agreement with previous studies.
