Abstract: A mathematical model is proposed for numerical simulation of the flow of the two superposed liquids (the electrolyte and molten aluminum) and of the electrolyte-metal interface wave. By employing a modified scheme based on the SIMPLE algorithm, velocities within both liquids and melt topography are calculated for a 280kA cell. Satisfactory results of numerical prediction are given.

Key words: aluminum reduction, k-ε turbulence model, numerical simulation
