Abstract

Behavior of growing/collapsing vapor bubble ejected to subcooled liquid bath was focused. Test fluid was purified water in the present study. Vapor bubble was produced inside the heated tube of 1.5 mm in inner diameter by supplying the test fluid to the tube by microsyringe. This system enabled the authors to observe interaction between the vapor and the liquid in the condensing process extracted from the boiling phenomenon consisting of liquid-gas-solid interactions. The bubble behavior was detected by employing a high-speed camera with up to 100,000 fps. The instability emerged over the surface of the growing and collapsing vapor is discussed as functions of the degree of subcooling, and the temperature and ejection speed of the vapor. The present study aims to understand and control the micro-bubble emission boiling known as MEB.
