对流阻尼是精确测量熔体扩散系数的关键，向熔体施加静磁场是在半导体和金属等导电熔体中实现阻尼的一种有前途的方法。基于有限元方法计算了均匀静磁场下低格拉霍夫数熔体的对流行为。利用该结果，通过数值模拟评估了扩散偶法扩散实验中的样本几何形状和施加磁场的方向。
Damping of convection is key in the precise measurement of a diffusion coefficient in melt, and applying a static magnetic field to the melt is a promising method of realizing damping in electrically conducting melt such as a semiconductor and metal. Convection behavior in a melt with a low Grashoff number under a uniform static magnetic field was calculated on the basis of the finite element method. Using the results, the specimen geometry and the direction of the applied magnetic field in diffusion experiments with a diffusion-couple method were evaluated by the numerical simulation.
