In previous publications, it was rationalized that a large vertical potshell deformation may have a negative impact on the operations of very high amperage cells. The MHD-Valdis non-linear Magneto-Hydro-Dynamic model was therefore extended to take into account the displacement of the potshell. The MHD cell stability behavior of a 500 kA cell with a 17.3 meters long potshell was then studied. This work is part of a long-term collaboration effort by the authors to investigate if there is a technical limit to the size of an aluminum electrolysis cell that can be successfully designed, built, and operated. The study highlights crucial factors such as heat dissipation requirements and MHD cell stability, arguing that as the cell size increases, thermal management becomes a significant challenge. The results suggest there are stringent limits imposed by MHD stability requirements, revealing that large vertical displacements of the potshell can adversely affect cell operation. By exploring these parameters, the research aims to contribute valuable insights toward optimizing aluminum electrolysis cell design.
