稀土熔盐电解槽内温度场数值模拟

Numerical Simulation of Temperature Field in Rare Earth Electrolytic Cell

在前人电场及流场的研究基础上,考虑电热场及电解质流动对温度场分布的影响,利用差分法建立柱坐标下的能量传输方程的上风差分离散格式,采用FORTRAN97编程,对3kA钕电解槽的温度场进行了数值模拟。结果表明,电极之间的发热强度最大,但并不是电解槽的最高温区,高温区在接收器内部(1 100℃),模拟结果与实测结果比较吻合。

Based on the electric field and flow field in previous research, considering electric field and electrolyte flows on the impact of temperature distribution, the 3 kA Nd electrolyzer temperature field was simulated using FORTRAN97 program, the upper hand differential equations about the energy transfer discrete format using finite difference method in cylindrical coordinate was established. The results show that high temperature zone is in the internal receiver （1 100 ℃）, the greatest strength of heat emitting is among the electrodes, the simulation results coincide with measured temperature distributions in real rare- earth electrolyzer.
