Abstract
An experimental study of nucleate pool boiling heat transfer was carried out over a pressure range between 4.70 psia to 3 atmospheres pressure in order to understand the effect of pressure upon boiling heat transfer. Degassed, distilled water was used as the boiling fluid. Experimental data were obtained from high speed motion pictures, consisting of number of bubbles (N) on the heating surface, bubble departure diameter (Db) and frequency of departure (f). Heat transfer rate was obtained from a wattmeter connected between power source and heater, and independently by calculation employing a measured temperature gradient within the heating rod. [...]
