Abstract
The electrostatic levitation is utilized as one of the containerless processing techniques. Some recent investigations focus on thermal property measurement of high temperature molten metals with an oscillating droplet method. For example, viscosity has been estimated from the damping constant. However, this method is limited to the low viscosity fluid. Thus, the purpose of the present study is to develop method of wide viscosity measurement on a levitated liquid droplet. In the present study, the droplets with kinds of viscosity were levitated by the electrostatic force. Droplet deformation was induced by applying rotation. The followings are obtained connection rotational breakup and viscosity. The observed dynamics indicated that it is possible to measure physical property of levitated droplet.
