Abstract
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.
