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)
