The magnetohydrodynamic (MHD) wave instability in commercial cells for electrolytic aluminium production is often described using 'shallow water' models. This study aims to extend the model for a variable height cathode bottom and anode top to account for realistic cell features. A systematic approach is employed to analyze how the variable depth of the two fluid layers affects the horizontal current density, wave development, and stability threshold within the electrolytic cells. Instructive examples for a 500 kA cell are presented to illustrate the findings. The results demonstrate that the proposed modifications to the model provide a more accurate representation of the behaviour of the MHD waves and their stability in relation to the unique variable structures encountered in aluminium electrolysis processes. This research contributes to the understanding of the dynamic interactions in such systems and may lead to improved efficiency and reduced energy costs in the aluminium production industry.
