Abstract
It is expected to manufacture new materials with container-less processing by levitation techniques. However, it is indicated that the levitated droplet with levitation technique has nonlinear behavior. In this study, nonlinear dynamics of the levitated droplet is experimentally and analytically investigated. The levitation experiments with the ultrasonic levitator and electrostatic levitator are conducted under the reduced and normal gravity condition. Based on the experimental results, theoretical analyses are compared to clarify the nonlinear dynamics of the levitated droplet. Furthermore, new technique to manipulate the thermofluid process of levitated droplet and measure the viscosity in high viscosity region are proposed by levitation techniques.
