INVESTIGATION OF THE INFLUENCE OF THE PHYSICAL PROPERTIES OF A LIQUID ON CRITICAL HEAT FLUXES UNDER BOILING
Abstract
Numerous tests on various liquids established that maximum critical heat fluxes were equal for all practical purposes in the case of boiling on horizontal plates 3 to 10 inches in height and on plates with their surfaces directed upward. Curves q(cr) = f (p) for methanol, propanol, and all other liquids are maximum at a pressure equal to 1/3 p(cr). The critical load increases (in comparison with the q(cr) for atmospheric pressure) by a factor of 2.3 to 2.8. The experimental data obtained are in good agreement with the generalized criterial equations proposed in the work of Sterman. Values of q 9cr) obtained on plates covered with C are 12 to 15% greater than those obtained on clean surfaces. Sterman, L. S., Zh. Tekh, Fiziki, Vol. 23, No. 2 (1953). (Author)
