本文提出了一种新的数值方法来分析交变磁场作用下导电液体的大变形。其主要特点是两个数值工具的特点：水平集方法，以稳定计算变形的自由表面和混合有限元法和边界元法，有效地离散电磁场。对导电液滴变形进行了二维数值模拟，验证了本格式的有效性，并研究了与表面张力和洛仑兹力大小有关的振荡行为.版权所有© 2004年约翰威利父子有限公司。
A novel numerical scheme for the analysis of large deformation of electrically conducting liquid under alternating current magnetic fields is presented. The main features are characterized by two numerical tools; the level set method to calculate deformed free surface stably and the hybrid finite element method and boundary element method to discretize the electromagnetic field efficiently. Two‐dimensional numerical simulation of conducting drop deformation is carried out to demonstrate the effectiveness of the present scheme, and the oscillatory behaviour, which depends on the magnitude of surface tension and Lorentz force, is investigated.
