Abstract

With the increase in line current and decrease in bath volume of aluminum smelting cells, alumina distribution is critical to cell performance. A VOF-DPM model with four flat anodes was developed to simulate the distribution, and can track both the gas–bath interface and dispersed alumina particles. The results show that alumina is more likely to accumulate in the anode gaps, and from there travels to side channels. More than 20 min are needed for the fed alumina to reach the concentration equilibrium; the alumina gradient in the transversal direction of the model exceeds that in the longitudinal direction.
