300 kA铝电解槽电、磁、流多物理场耦合仿真

将标量电位法和磁标量位法相结合，开发了铝电解槽电场、磁场耦合计算模块，并导出了电磁力场以计算磁流体三维湍流流场及其界面波高. 计算结果表明，垂直磁场基本呈现为反对称关系，水平电流对磁流体运动有显著影响，铝液流场形态基本对称，呈现为4个较大漩涡，铝液界面向中部隆起. 将计算结果与测试值进行了比较，表明该方法能够有效用于铝电解槽生产和设计的物理场仿真计算分析.

Coupled Simulation of Multiple Physical Fields in a 300 kA Aluminum Electrolysis Cell

The method of nodal voltage analysis and magnetic scalar potential method were utilized to develop a customized program to model the coupled electromagnetic and flow fields in a 300 kA aluminum electrolysis cell,and the flow field was simulated with the derived electromagnetic forces.From the modeling it was shown that the asymmetry of the vertical magnetic component was obvious along the x and y axes while the horizontal current exerted significant effect on the magnetic fluid flow when interacting with the vertical magnetic field.There were four large vortexes in the liquid aluminum.The calculated results were compared with the measurements.
