A mechanism supported by extensive experimental evidence to explain high heat fluxes observed during nucleate boiling

摘要: The mechanism responsible for high heat transfer rates occurring in nucleate boiling when liquid films exist on the heating surface is described. High-speed cinematography and simultaneous transient temperature measurements provide a basis describing mechanism. In film, bubbles grow detach rapidly. film quickly renewed. A microlayer exists beneath bubble its entire life. Conditions are very favorable rapid evaporation from so that rapid. number of independent observations by other investigators working diverse problems cited support
