Abstract

© 2016 by Begell House, Inc. The phase change heat (hfg) plays a fundamental role in the description of the film boiling phenomena and, therefore, is included in most of the correlation to evaluate film boiling heat transfer coefficients. The Jakob number (Ja) is used to establish the ratio between hfgand the sensible heat required to heat the vapor formed from the saturation temperature of the surroundings to the emperature on the solid-fluid interface. In the most accepted correlations, the enthalpy increase in the fluid is described with a scaling factor of hfgbased on a fraction of Ja. In literature, this fraction varies from 0.34 to 0.95. In this paper, a numerical prediction of the mean temperature of the vapor film and this fraction were done based on computational fluid dynamic (CFD) calculation. Our analysis of the vapor film temperature shows that this Ja fraction is of the order of 0.4, with a small dependency of the emissivity and Prandtl number.
