A CFD based numerical model for a realistic generic aluminium reduction cell is published. The model takes into account the complex physics of the magnetohydrodynamic problem in the reduction cell by coupling of two immiscible liquid flows, Lorenz force, flow turbulence and large length-scale with complex cell geometry. The current model extends the traditional box model with a detailed cell geometry including side and bottom ledge profiles and all channels (side, central and cross channels). The simulation tests of this model focus on quantifying the sensitivity of different side and bottom ledge profiles, and the cross channel by comparing the resulting metal flow and metal pad heaving. In addition, the model dependencies upon model assumptions of open/closed channel top are discussed. Finally a physical mechanism for the metal pad heaving that seems to explain at least parts of this complex phenomenon is highlighted.
