摘　　要：对稀土电解槽内颗粒的运动轨迹进行模拟。对电解槽的流场采用欧拉方法进行模拟,在流场收敛后加入不同直径的颗粒,采用拉格朗日方法对颗粒的轨迹进行模拟。结果表明,颗粒均做弯曲向上的运动,到达电解槽溶液上表面,漂浮于液面上,粒径不同运动的轨迹和到达液面的时间也不相同。Trajectories of particles in rare earth electrolytic cell were simulated. Flow field of electrolyzer was simulated by Euler Method. Particles with different sizes were added into flow field after its convergence. Trajectories of particles were simulated by Lagrange Method. The results of particle trajectories show that particles move to upper surface of electrolyte solution and float in liquid surface. Particles with different sizes have different motion trajectories and different time spent to reach upper surface.
