• Generation Behavior of the Micro Bubble

抄録

The purpose of this research is to visualize 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 water droplet collided on a sapphire heating surface. In the heating sapphire surface temperature range from 150℃ to 220℃, especially, the generation behavior of the vapor bubble was photographed from the back of the sapphire heating surface by a high-speed video-camera. It was observed that the bubble generation behavior changes with the heating sapphire surface temperature. As the temperature become higher, the generating period of the bubble becomes early and the growth cycle of the bubble becomes short. When the initial heating surface temperature exceeds 200℃, the bubble locally unites. Next, the coalescent bubble grows, and it collapses and scatters.
