Abstract

"A maximum heat flux correlation was derived for corresponding states liquids and subsequently verified by the data collected in this study as well as data presented in the literature. By applying this correlation, one can predict maximum heat flux values at high pressures from maximum heat flux values measured at low pressures; however, to apply the correlation it is necessary to have at least one maximum heat flux value and the saturation temperature at which it was determined.

Contrary to existing correlations, it is shown that for any nucleate boiling heat transfer correlation to be truly general, it must include heat transfer surface and possibly geometric properties. When the data were compared to several common maximum heat flux correlations, severe differences between the data and the correlations were displayed.

Nucleate pool boiling heat transfer studies were conducted under varying conditions in heat transfer surface, geometry, and medium. Liquid nitrogen and liquid argon were boiled on copper, gold, chrome, and "teflon" cylinders which had diameters of 0.75 and 0.95 inches and lengths of three inches. The studies were carried out at pressures ranging from atmospheric pressure to near the critical pressure of each of the two fluids. These studies provided the data used to validate the maximum heat flux correlation and illustrate the surface and geometric effects on the nucleate boiling curve"--Abstract, page iii.
