Abstract

A theoretical analysis of pool film boiling based on a cellular model is presented. The time-averaged cell configuration is postulated to adjust itself to maximize the rate of heat transfer. Theoretical expressions for the heat-transfer coefficient, average vapor dome (bubble) radius, and optimum cell diameter (wavelength) were in close agreement with experiments. As a generalization of this work and others, a tentative nonequilibrium thermodynamic hypothesis is proposed that nature maximizes the entropy production in all situations characterized by macroscopic chaos.
