Abstract
In this study, we investigate the deformation of the levitated droplet using a YAG pulsed laser and the possibility of the measurement of its thermo-physical properties. The sample was levitated by using an electrostatic levitator (ESL). The behavior of levitated droplet was observed by high-speed camera that has been installed on the side of ESL chamber. A hole on the droplet was provided by the laser radiation pressure. During the relaxation of deformation, a small liquid drop (satellite) jumped out from the levitated sample. The size of satellite drop depends on the power of the YAG-laser. Weber number was estimated when the satellite droplet was formed. The Weber number at satellite formation was similar to the experiment on the International Space Station.
