Conditions of Onset of Boiling in a Vertical Thermosiphon Reboiler

摘要

An analysis of the incipience of nucleate boiling for a vertical thermosiphon reboiler was developed as a modification and extension of earlier analysis. The maximum superheat attained around the onset of boiling was taken from the wall-temperature distributions and correlated with heat flux, submergence, and physical properties of the test liquids. The results predicted from theoretical analysis are consistent with the experimental data that are available in the literature. All of the data for the eight fluids tested, each having different thermophysical properties, were correlated with a single correlation having an average absolute relative error of 21.35%.
