Abstract Scope In the Hall-Héroult electrolysis cell for aluminum production, understanding hydrodynamic phenomena induced by the magnetic field is very important for process stability and performance in terms of aluminum production and energy efficiency of the cell. The study of these phenomena requires mathematical modeling of the flow of liquid aluminum and the electrolytic bath under the operational conditions of the cell. The problem involves solving two equations systems for two immiscible stratified fluids where the movement is primarily subject to the effects of gravity, pressure force, shear stresses and of course the electromagnetic forces. The characteristic length scale of flow is very different in the three directions of the cell geometry. Then the turbulence estimation for flow modeling is an arduous task. In this study, numerical investigations are made in order to investigate the applicability of Large Eddy Simulation turbulence models to represent well the magnetohydrodynamic turbulence in the electrolysis cell.
