Abstract
The purpose of this research is to clarify the mechanism of the miniaturization-boiling phenomenon, which intensely scatters with a large number of minute liquid particles from a water droplet surface to the atmosphere, when the droplet collided on a heating surface. Generation, coalescence and injection of the micro bubble in a superheated liquid film cause the generation of the miniaturization boiling. Then, a sapphire surface was used as a heating surface in order to catch this micro bubble, and the solid-liquid contact behavior on the droplet collision was photographed by a high-speed camera from the back surface.
