Abstract
This paper reports the mathematical modelling of electrochemical processes in
the Søderberg aluminium electrolysis cell. We consider anode shape changes,
variations of the potential distribution and formation of a gaseous layer under the
anode surface. Evolution of the reactant concentrations is described by the
system of diffusion-convection equations while the elliptic equation is solved for
the Galvani potential. We compare its distribution with the CO2 density and
discuss the advantages of the finite volume method and the marker-and-cell
approach for mathematical modelling of electrochemical reactions.
Keywords: aluminium reduction, electrochemical reaction, gaseous layer,
mathematical modelling, finite volume method.
