摘要 空泡率是汽液两相流动的基本参数之一。在计算空泡率的众多模型中 ,Zuer Findlay漂移流模型目前应用最为广泛。根据受热工况下局部界面参数径向分布特性实验研究结果 ,并通过对现有实验数据的处理 ,分析了受热工况下垂直上升两相流漂移流模型分布参数C0 随截面平均空泡率的变化规律。证实了从过冷沸腾泡状流到饱和沸腾弹状流工况 ,随着空泡率的增加 ,分布参数C0 从一个小于 1的值增加到 1 .0~ 1 .2。 Void fraction is a key parameter in two-phase flow. In the calculation of void fraction, Zuber-Findlay drift flux model is the most famous one. This paper studies the influence of average void fraction on distribution parameter C 0 for drift flux model in an upward heated two-phase flow, based on the analysis of experimental results of local interfacial parameters radial distribution and process of existing experimental data. The investigation shows that C 0 increases from a number less than 1 to 1.0~1.2,as the increase of average void fraction, in bubbly and sluge flow.
