Current Distributions and Electrode Shape Changes in Electrochemical Systems

Current Distributions and Electrode Shape Changes in Electrochemical Systems Synopsis

This volume is published in response to the increasing demand for computer modelling of electrochemical processes in order to improve their speed and efficiency. The fundamental transport equations in dilute solutions are introduced and it is established in detail under what circumstances a potential model with non-linear boundary conditions, involved in electrode reactions, can be used. A survey is given of the most important solution techniques, FEM, FDM and BEM, and the solution of non-linear systems of equations by successive substitution and Newton-Raphson method is treated.;Using the BEM, several two-dimensional and axisymmetrical examples of current density distributions are given and quantitative data, obtained in a copper electro-refining cell, are compared with calculated results. Applying Faraday's law and the BEM, the simulation of electro deposition, electrochemical levelling and electrochemical machining are treated with an emphasis on accuracy and stability.
