摘要
针对铝电解槽内电解质/铝液界面的波动现象,基于计算流体动力学(CFD)的方法建立了铝电解槽内电解质/铝液两相流体流动的数学模型.使用Fluent软件的流体体积自由面跟踪法和自定义函数,研究了阴极凸台对电解质/铝液界面波动的影响.结果表明,异型凸台的加入使得两相界面的波动幅度降低了17.2%,但凸台的存在同时也使得熔体对侧部槽帮冲刷增强.
Reducing electric energy consumption of an aluminum reduction cell requires shortening of the anode-cathode distance(ACD),which requires a lower magnitude of liquid aluminum wave.A mathematical model of electrolyte/aluminum two-phase flow in reduction cells,based on a 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 magnitude of the two-phase interface wave was reduced 17.2% for cathode convexes,while also enhancing washout of the melt on the ledge.
