摘要
The standard approach which relates heat transfer in nucleate boiling to heal transfer to the superheated layer averaged over the time between two successive departures of a bubble from a given site is extended in order to relate the heal flux to the wall superheat through the heating surface characteristic. It was found that the q/A versus δT relation depends on the cavity size distribution over the surface. For a known distribution of cavity size, the q/A versus δT relation, may be predicted, or for unknown characteristics of the boiling surface it is sufficient to have boiling data at one pressure in order to predict the q/A versus δT relation of other pressure levels for the same surface and the same liquid. The latter was tried on a wide range of experimental data including water and three organic liquids with good results. © 1969 by ASME.
