摘要
对空气－水混合物在壳侧沿水平方向横掠垂直管束的两相流流型及其转变特性进行了实验研究，管束为正方形顺排，管间距与管径之比为１．２８．对两相流流型进行了仔细的观察，并对流型进行分类，作出了流型圈，提出了各种流型转变的机理及相应的判别流型转变的无量纲准则式。
An experimental study has been conducted to determine flow patterns and their transi-tions in horizontal crossflow across a vertical tube bundle. The experimental work reported is carried out by using air-water mixtures in an in-line tube bundle with pitch-to-diamiter ratio,P/D,of 1.28.The flow patterns are observed and a flow pattern map is made, Models anddimensionless correlations are presented to determine flow region transitions。
