Outline of Final Research Achievements

The present research studies the mechanism of periodic bubble nucleation and departure from hydrophobic surface under subcooled condition. We focus on dissolved air into boiling liquid as the governing factor. We performed two types of experiments. One is with dissolved air (Open condition) and the other is without air (Closed condition). The results are summarized as follows; There was no bubble generation in closed codition, and it was found that the bubble consists of a mixture of water vapor and air. The dissolved air enhances boiling heat transfer right after onset of boiling.
