Abstract

A general software framework for the solution of electrochemical processes will be presented.

In a first part the set of equations that are considered is given. Then it is explained that frequently used models are in fact subsets of these equations covering ion transport, electro-osmotic flow on micro- and nanometer scale, electrophoresis, MHD effects, ion transport influenced by a magnetic field. etc. .

It is further explained how the structure of the software is conceived in order to obtain a flexible tool. The main idea is that blocks of one or several equations can be solved in an almost arbitrary sequence. For instance strongly coupled fields like flow and pressure or ion transport and electro neutrality are solved simultaneous in one system whereas the temperature field is often treated separately such that the interactions of the temperature on all physical parameters (viscosity, density, etc.) are considered in what is called weakly coupled iteration loops.

Then aspects of numerical discretisation and also grid generation are highlighted. Finally typical examples will be treated, showing the power of the framework. Ion transport in laminar and turbulent transport, electro-osmotic flow, magnetic influences on ion transport and also the highly temperature dependent anodizing process.
