Coupled Simulation Of Multiple Physical Fields In A10kA Rare Earth Electrolysis Cell

The electrolysis cell with parallel insertion of cathode and anode structure exposedmany problems in the process of production, so the researchers has been to explore thedevelopment of new type of electrolytic cell. This is a kind of cell called bottom-cathode-structure electrolytic cell. On the basis of previous studies, inspecting the practicability ofthis electrolytic cell in depth. This paper will calculate the electric field, magnetic field andthe electromagnetic motion under the influence of electrolyte by using numerical simulation.Firstly, the ANSYS is used to calculate the electric field and potential distribution ofbottom-cathode electrolytic cell, including the pole pitch is11cm,12cm,13cm,14cm,15cm.Using direct coupling method to calculate magnetic field distribution in electrolytic cell. Theresults show that:(1)The current through the area between anode and cathode is focus, theintensity of electric field is most intense, the potential gradient is larger, the electric fieldintensity is bigger also.(2)The electric field distribution is the most intensive and paralleldistribution between the cathode and anode, and this is relatively thin between anode andtank wall, decreased from the lower to the upper. The voltage of melt is increase when thepole pitch increased, but the electric filed intensity is decreased.After calculating the electric field and magnetic field, electromagnetism will be as theloading to the fluid. Indirect coupling method is used to calculate the movement under theinfluence of the electromagnetic force. Although the current strength is small in10kAelectrolytic cell, it has its practical significance. It is the prophase preparation work oflarge-scale development of bottom-cathode electrolytic cell. The electrolyte move to thecenter of model under the electromagnetic force.
