| Research Abstract |
When a liquid droplet impacts on a superheated surface, a localized liquid-solid contact appears on the surface, which is to be expanded, limited and extinguished. This research aims to reveal the mechanisms of this phenomenon. Firstly, liquid-solid contact situations were visualized from below the surface and recorded into high speed video camera. Liquid-solid contact diameter and number density of nucleation sites were measured by image processing. T hen, based on these visualization measurements results, the numerical simulation program was made to calculate transient heat transfer process during intermittent localized liquid-solid contact occurs on a superheated surface. This program can calculate temperature distribution and its temporal change of the superheated plate. Through visualization experiments and numerical simulations, the process during which a localized liquid-solid contact is limited on a superheated surface was physically grasped.
