Abstract
In an aluminum reduction cell, bubbles are generated on the anode surfaces. Before they get out of the bath, they linger over between gap of the anode and the cathode, which leads to additional voltage drop. The alumina concentration adjacent to the anode is also affected. How are the bubbles formed and what kinds of shape they have are the important issues. Numerical simulation can provide detailed information about bubbles. The volume of fluid model (VOF) was applied in the bubble simulation. The flow difference between different locations was presented.
