Condensation and Collapse of Vapor Bubble Injected to Subcooled Pool

摘要

We try to extract the vapor-liquid interaction by employing a vapor generator that supplies vapor at designated flow rate to the subcooled pool through the orifice (Fig. 1), instead of using a immersed heated surface to realize a vapor bubble by a boiling phenomenon. This system enables ones to detect a growing, condensing and collapse processes of a single vapor bubble (Fig. 2). Temperatures of the liquid in the pool and injected vapor are controlled to realize a designated degree of subcooling, ΔT_(sub). Vapor injection rate is another controllable parameter in this system.
