For analysis, the MHD electrolyzer was adapted to a three-dimensional mathematical model, which uses a multiphase approach to the description of the medium (aluminum, electrolyte and gas), as well as to hydrodynamic, electromagnetic, thermal and electrochemical processes in the bath. Test calculations were carried out, which confirmed the model adequacy and the presence of the proposed numerical solutions to the problem with sufficient accuracy. The suggestion that the Soderberg electrolyzer is less MHD-stable than the multi-anode electrolyzer was confirmed. The impact on the MHD stability of various initial configurations forms has been assessed. The influence of a potential change on the MHD-stable form of the bath working space is investigated.
