摘要: Based on the analysis of the principles of heat and mass transfer from the liquid
bulk to bubble surface during nucleation, a new estimation method to predict the heat
transfer of the nucleate pool boiling in binary mixtures is proposed in this paper by using
the heat and mass transfer analogy (Colburn analogy) at the bubble surface transfer layers.
With the use of Thome’s concept of boiling range, an approximate method is derived to
realize the calculation. The predicted results by this method are in good agreement with
the experimental data from different sources.
