Abstract:

The objective of this research project was to study the effect of small artificial cavities on both natural convection and the incipience of saturated pool boiling from a horizontal test surface. All tests were run with distilled Freon 113. Data for the heat flux as a function of the superheat and the convection heat transfer coefficient as a function of the heat flux were carefully obtained and plotted. Experimental results are presented for the heat transfer from horizontal circular disks, with and without artificial cavities. Increases in both natural convection and boiling heat transfer were observed with the addition of artificial cavities. The magnitude of heat transfer augmentation was found to be strongly dependent upon the artificial cavity density. Author
