本研究的目的是建立(1)非导电液体在材料加工中的悬浮过程和(2)医学领域中的药物在血管中的输送技术。利用由硅油液滴和磁性液体组成的简单模型，实验观察了抗磁液滴在非均匀磁场中的行为。考察了磁场强度、磁场分布、液滴体积、密度和表面张力对非磁性液滴悬浮形状和位置的影响。然后，在不同条件下进行了数值分析，明确了主导的无量纲参数。实验结果与数值计算结果吻合较好。
The purpose of the present research was to establish (1) the levitation process of a nonconducting liquid in material processing and (2) the drug transportation technique in blood vessels in the field of medicine. In this study, the behavior of a diamagnetic liquid droplet in nonuniform magnetic field was observed experimentally using a simple model consisting of a silicone oil droplet and a magnetic fluid. The influences of magnetic field strength, magnetic field distribution, droplet volume, density and surface tension of magnetic fluid on the shape and position of nonmagnetic droplet levitation were examined. Then, numerical analysis was carried out under various conditions to clarify the dominant nondimensional parameters. The experimental results and the numerical ones showed in good agreement.
