Numerical investigation on the impacts of the novel cathode convex on the electrolyte/aluminum interface wave in reduction cells

摘要：

To lower the electric energy consumption of aluminum reduction cell, the anode-cathode distance (ACD) needs to be shortened, which requires less of liquid aluminum wave. A mathematical model on the electrolyte/aluminum two-phase flow in reduction cells is presented, based on the computational fluid dynamics (CFD) method and the commercial software Fluent, was developed to study the impact of the cathode convex on the electrolyte/aluminum interface wave. The results showed that, the magnitude of the two-phase interface wave was reduced by about 17.2％ with novel cathode convexes, while at the same time, the washout of the melt on the ledge was also enhanced.
