Abstract

Abstract: Two mechanical models——recirculating flow and sliding bubbles, which lead to the bundle effect in nucleate boiling on tube bundle are established and calculated quantitatively. The correlation of nucleate boiling on tube bundle is put forward on the basis of experiments, and the influence on boiling heat transfer is analysed.

摘要： 对管束核态沸腾引起管束效应的对流循环和滑移汽泡两种机制作了模型假设和定量计算。并在实验基础上拟合了管束核态沸腾平均换热系数计算公式,分析了两种机制对换热的影响。
