概要

• 論文の詳細を見る

• Experimental and theoretical studies were made upon the configuration and detaching behaviors of an isolated vapor bubble in saturated nucleate boiling of water and ethanol. The dynamic contact angle was found to vary sharply as the bubble grows, so it should be concluded that the concept of contact angle can't be directly applied to the discussion of boiling heat transfer. The boiling rate at an individual nucleation site, namely D_df was predicted to be dependent upon heat flux and good agreement was obtained with experimental results. Further, many other data were newly obtained concerning the bubble shape and detaching characteristics.
