摘要:

对液态金属自由表面膜流在强磁场下的磁流体力学效应进行了数值模拟研究,获得了液态金属自由表面的形状、截面流速分布及截面上的电动势分布,从而能对膜流的一些磁流体动力学行为作出解释。数值计算结果与理论分析和实验结果符合较好。由实验和数值模拟结果可以得出,液态金属膜流通过强磁场时,磁场会阻碍膜流的运动。

Abstract:

Numerical simulation is implemented to analyze magnetohydrodynamics (MHD) instabilities of liquid metal (LM) free surface film-flow, which is flowing in a strong magnetic field. The shape, velocity and electrical potential profile in the cross-section of the film-flow are also given. Thereby the MHD behavior of LM free surface film-flow can be well explained. The numerical simulation results are in good agreement with experimental data. The results show that the magnetic field may hinder the liquid metal film-flow from motion when it flows through a strong magnetic field.

Key words: Magnetohydrodynamics, Free surface, Film flow, Liquid metal, Numerical simulation
