Description

The objective of this project is to develop and evaluate reliable numerical methods to predict the current density distribution and consequently the deposition of reacting species in electrochemical systems of various natures and industrial relevance. In these systems mass transport phenomena of charged species due to diffusion, convection and migration (electrical forces) are strongly coupled with the electrochemical reaction(s) at the electrodes. The main objectives are: Development of numerical methods for solving the governing system of equations in three dimensions. This system results from the combination of the mass and charge transport equations with the uncoupled Navier-Stokes equation. Development of numerical methods in two dimensional and axisymmetrical systems for theoretical description of electrochemical systems with more complex electrode processes: multicomponent solutions, homogeneous reactions in the bulk, parallel charge transfer reactions (e.g. to model alloy plating) and electrode growth. Development of numerical methods in two dimensional and axisymmetrical systems for theoretical description of electrochemical systems where the following phenomena are relevant: ohmic and temperature effects in electrodcs, ohmic and temperature effects in the solution, temperature effects produced by electrode processes, interaction between fluid flow, heat, mass and charge transfer. Experimental determination of flow, mass transport, current density, thickness, temperature and potential distributions. Comparison of measured and calculated data with evaluation of the limits of applicability.
