基于ANSYS Workbench的铜电解槽多物理场耦合仿真

以国内某厂铜电解槽为对象,基于ANSYS Workbench协同仿真平台,构建Maxwell和Fluent仿真模块的多场耦合仿真环境,探究槽内电场和流场的分布情况。结果表明：铜电解槽内高密度电流及电损耗功率主要集中在极板间区域;阴阳极板可以视作等势面,阳极板端部电流矢量方向由端部向外扩散,电场梯度均匀;根据流场分布特征可将铜电解槽内流体区域分为四个区域,其中阴阳极板之间区域的电解质流量仅为9%左右,槽底存在约1%的流动“死区”。

Multi-Physical Field Coupling Simulation of Copper Electrolyzer Based on ANSYS Workbench

Based on the collaborative simulation platform of ANSYS Workbench, a multi-field coupling simulation environment of Maxwell and Fluent simulation modules was built to explore the distribution of electric field and flow field in a copper electrolytic cell in a domestic factory. The results show that the high density current and electrical loss power in the copper electrolytic cell are mainly concentrated in the area between the plates. The cathode and anode plates can be regarded as equipotential surfaces. The current vector direction at the end of the anode plate diffuses outward from the end, and the electric field gradient is uniform. According to the distribution characteristics of the flow field, the fluid field in copper electrolytic cell can be divided into four areas. The electrolyte flow rate in the area between the cathode and anode plates is only about 9%, and there is about 1% flow "dead zone" at the bottom of the cell.
