Abstract
A numerical study of the role of the electrodeposit geometry on the electroconvective motion in a thin
electrodeposition cell is presented. The transport phenomena are described in terms of evolutionary twodimensional
Nernst-Planck equations for cation and anion concentrations, the Poisson equation for the electric
field and Navier-Stokes equations for the laminar fluid flow. The simulations are performed for different
geometries of the cathodic electrodeposit in order to emphasize its influence on the electrically driven
convection. The predicted concentration, electrostatic potential and flow patterns are in qualitative agreement
with typical electrodeposition experiments.
