| 摘 要： | 为了对铝电解槽内磁流体的两相流动和界面波动进行深入了解，通过ANSYS和CFX相结合的方法，把洛伦兹力作为动量源相，对160kA铝电解槽内的磁流体流动进行了两相流数值仿真.仿真结果表明：铝液和电解质的流动均呈两个漩涡；铝液的平均流速为0.1476m/s，最大流速为0.2879m/s；电解质的流速偏小，平均流速为0.1165m/s，最大流速为0.286.6m/s；电解质和铝液的界面变形范围为-0.029~0.035m.将流速计算结果与实测值进行了对比，表明对基于两相流动的铝电解槽内磁流体进行数值仿真可以帮助了解铝电解槽内的流场，为进一步优化研究提供了依据.

| Abstract: | In order to understand both two-phase flow and interfacial fluctuation of magnetic fluid in an aluminum electrolysis cell,the two-phase flow numerical simulation for magnet fluid flow in a 160 kA aluminum electrolysis cell was performed through combing ANSYS with CFX software and taking Lorentz force as momentum source phase.The simulation results show that the flow of both aluminum liquid and electrolyte exhibits two vortexes.The average and maximum flow velocities of the aluminum liquid are 0.147 6 m/s an... |
