Abstract
We investigated the interfacial behavior and atomization of an acoustically levitated droplet. It is vital to understand quantitatively the non-linear dynamic behavior of such the interface deformation and translational motion of the acoustically levitated droplet in order to apply acoustic levitation method to the various scientific fields. The purpose of our study is to investigate experimentally the interfacial behavior and atomization of droplet. In this paper, we recorded its time evolution from the interfacial deformation to atomization by high speed video camera. We estimated the dynamics of the droplet quantitatively with three different levitated liquid samples and compared with the experimental correlation by Danilov. et al.. It is shown that the mechanism of the atomization of the levitated droplet is more complicated than the existing model indicated by the theory.
