建立了半浮区法液桥在静磁场作用下的物理数学模型，并进行了不受重力影响的数值模拟。控制方程为N-S方程结合能量守恒方程，由SIMPLE算法计算。在交错网格上，采用水平集函数和连续曲面力（CSF）模型捕获自由曲面。结果表明，在一定的静磁场强度下，不同的两盘温差和不同的液桥宽高比对自由表面变形和内部速度场都有不同程度的影响。
The physical and mathematical model of the liquid bridge in half-floating zone method which is exposed to static magnetic field is built and numerically simulated without the effects of gravity. The governing equations are N-S equations combined with the conservation equation of energy which is calculated by the SIMPLE algorithm. On a staggered grid, the level set function and the continuum surface force (CSF) model is adopted to capture the free surface. The result indicates that under certain strength of static magnetic field, different temperature differences between the two disks and different aspect ratios of the liquid bridge have influence both on the free surface deformation and inner velocity field in different degrees.
