Bubble Boiling Heat Transfer The Possibilities of a Theoretical Analysis
RÉSUMÉ
An analysis of the newest numerical investigations of elementary processes of bubble boiling (growth of a single bubble, flow and evaporation of thin liquid films at a nucleation site) is given. It is shown that these investigations, despite their usefulness for understanding the process, cannot be used for engineering calculations. In this respect, the development of approximate theories of bubble boiling that reflect substantial interrelations between the governing parameters is most advantageous. To refine computational boiling heat transfer equations, it is most important to substantiate theoretically the dependence of the number density of nucleation sites on the temperature difference and properties of phases.
