摘要
本文在对卧式螺旋管内气液两相泡状流动及其转变的特征进行详细的实验研究的基础上,以现象为根据建立了泡状流转变的模型,给出了全范围内泡状流转变的边界预报式,实验与理论结果符合得很好。模型考虑了离心力和重力联合作用下的机制,对于弯管和直管内流动,模型具有兼顾的性质。
In this paper,an experimental and theoretical research on thetwo-phase bubbly and dispersed.Bubbly flow and their transitio-ns characteristics is carried out in horizontal helically coiled tu-bes.Based on the observation phenomena and physical concepts,a general purpose mathematical model and criteria for the transi-tions are presented.From this theory,the transition boundariesat the various local positions in horizontal helically coiled tubeare predicted,and show good agreement with experimental results.
