Abstract
An analysis of the incipience of nucleate boiling is developed as a modification and extension of previous analyses. The results are compared with data for subcooled boiling of water in forced convection flow. Apparent anomalies in the data for the onset of boiling in two‐phase gas‐liquid flow are shown to be a result of a limited size range of cavities on the heater surfaces. Measurements of the surface characteristics of a copper heating tube were made and compared with incipient boiling heat transfer data taken in that tube. The results predicted from the theoretical analysis are consistent with the experimental heat transfer data.
