Abstract
通道内截面汽泡平均直径是计算两相流相间界面传递方程以及计算汽液相界面浓度的重要参数。综合考虑过冷沸腾工况下汽泡动力学、两相热力学以及汽泡聚合效应; 对通道内汽泡尺寸的影响,提出过冷沸腾通道内截面汽泡平均直径预测模型。将该模型与实验数据进行比较,预测值与实验值偏差12.5%。
 
Bubble mean diameter is a key parameter to calculate the interfacial; transfer equation of two phase flow and interfacial concentration.; Taking into account the effects of both the thermal, hydrodynamic; conditions and bubble coalescence rate on the mean bubble size in the; channel, a model has been developed. The proposed model agreed well with; the experimental data within the averaged relative deviation of 12.5%.
