| Abstract Scope |
This paper presents a novel air-water model designed to represent the dynamics of multiple bubbles in the Hall-Héroult process of aluminum smelting cells. Air bubbles are continuously generated beneath a small rectangular carbon anode specimen inserted into a water bath. The characteristics of bubble motion, including bubble size, bubble velocity, and bubble vorticity are examined and compared during two phases of bubble movement: a) sliding horizontally beneath the anode, and b) rising vertically into the downstream side channel. Furthermore, the impact of air flow rate on these bubble dynamics features during different stages of the bubble journey is evaluated for a slightly inclined anode. The findings showed that increasing the air flow rate increases the bubble size, resistance, vorticity, and velocity in the first period of bubble motion under the anode. In contrast, gas hold-up time under the anode decreases. |
