Abstract

Abstract: A comprehensive model for nucleate pool boiling has been developed to predict the effect of cavity size and cavity density on boiling heat transfer. The results of experimental investigations on surfaces with artificial nucleation sites confirmed the theoretical model satisfactorily.

摘要： 本文在前人提出的各种沸腾传热机理模型的基础上,建立了一个关于核状沸腾传热机理的综合模型,并在规则排列的、不同汽化中心密度和孔径的人工汽化中心表面上进行了沸腾传热实验,对所提出的模型进行了验证.模型计算结果与实验结果符合良好,文中根据所建立的模型分析了汽化中心的大小和密度对沸腾传热速率的影响.
