title = "Stability analysis of simplified electrolysis cells with MISTRAL",
abstract = "The control of the electrolysis cell stability represents a major stake in the primary aluminum industry. For that, many numerical models were developed generally by considering a linear stability approach. We studied the stability of a simplified electrolysis cell with an unsteady 3D model (MISTRAL) strongly coupling the equations of fluid mechanics and induction. Then we analyzed different specific magnetic configurations: stable and unstable. From the time evolution of the interface deformation associated with a spectral analysis (FFT), we could differentiate the stable cases from the unstable ones by comparing a growth factor, noted T. The metal pad rolling appears on cylindrical and parallelepipedic cells with important metal and bath height compared to the length and width of the cell but tends to disappear for much smaller ratios.",
