Numerical Modeling on the Fluid Flow-related Phenomena in an Aluminum Electrolysis Cell
Abstract
Water modeling and mathematical modeling were used to study the fluid flow-related phenomena in an aluminum electrolysis cell. the VOF multiphase fluid flow model was developed and validated by the water modeling - Laser Doppler Velocimeter (LDV) measurement in a full scale water model of the reduction cell. Effects of the slot design and the tilted angle of the anode on the behavior of bubbles under the anode were studied the slot under anode facilitates the escape of bubbles with flat bottom anode, the slot is the main releasing path for bubbles. Without a slot, a thicker gas film forms under the anode and this causes great energy consumption and induces violent fluctuation in the slot. by increasing the tilted angle of the anode, bubbles either escape from the slot or moves along the tilted anode bottom and finally escapes from the curved end of the anode.
