中文摘要：
针对熔盐电解法制取稀土金属钕槽型结构,首次提出了多孔介质模型与表面化学反应相结合的方法研究阳极电解反应过程,通过在靠近阳极表面取1~2mm的薄层设立为多孔介质层,并在多孔介质层上增设化学反应,模拟研究阳极表面的化学反应、槽体内部流场运动情况以及气泡上浮过程,同时对比欧拉法的模拟结果得到了该模拟法与欧拉法模拟的区别及该法研究的优势。模拟结果表明,该方法更能反映实际电解过程气泡生成和运动规律。
英文摘要：
Anode electrolytic reaction process was studied for the first time by combination of porous medium model with surface chemical reaction model with regards to structure of rare earth electrolysis cell used to produce neodymium metal by electrowinning.By setting porous medium layer within 1~2 mm thickness near anode and adding chemical reaction on porous medium layer,chemical reaction on surface of anode,flow field inside tank and gas bubble floating movement of process were simulated.Difference between this simulation method and Euler method and advantage of this research method were summarized by comparison.The simulation results show that this method can better reflect bubble generation and motion law of actual process of electrolytic reaction.
