"An investigation of film boiling heat transfer in saturated pools of liquid Freon 113, Normal Pentane, Cyclopentane, and Benzene was made. The fluids were boiled from copper, cylindrical heat transfer surfaces, 3 inches long, and 0.55, 0.75, and 1.00 inch in diameter. The heat transfer elements were positioned horizontally in an autoclave and tested at moderate pressures of up to a pressure of 242.5 psia for Normal Pentane.
The experimental data are discussed and compared with known film boiling correlations. The known correlations were found to be inadequate in predicting heat transfer coefficients as a function of pressure, temperature difference between the heater surface and the fluid, surface diameter, and the type of fluid boiled. For instance, a correlation by Sciance predicts the experimental heat transfer coefficients, h, of this investigation from within 3% error to as much as 50% error. A correlation by Chang predicts values of h that vary by a factor of 3 from the experimental values of this investigation. The h values predicted by the correlations of Baumeister, Breen and Westwater, Pomerantz, Bromley, and Berenson deviate from the experimental values by percentages between those of the Sciance and Chang correlations depending on the pressure of the system, diameter of the heater surface, and the fluid under investigation.
A correlation for film boiling is derived and discussed"--Abstract, pages ii-iii.
