Abstract

A BEM model for convection- diffusion- migration problems in binary electrolytes Z.H. Qiu, L.C. Wrobel & H. Power Wessex Institute of Technology, University of Portsmouth, Ashurst Lodge, Ashurst, 7A.4, INTRODUCTION This paper presents a boundary element scheme to predict the current density distribution and, consequently, the deposition of reacting species in electrochem- ical systems of various natures. This is a problem of interest to many branches of the electrochemical industry, like plating, etching, anodizing, machining, etc. In all these electrochemical systems mass transport phenomena of charged species due to diffusion, convection and migration of electrical forces are strongly cou- pled with the electrochemical reactions at electrodes. It is therefore necessary to develop reliable numerical methods which can take into account all these effects. In a first stage, only binary electrolytes consisting of two ions are considered. In this case, th
