摘要

设计了一种新型三通型两相分配器

该分配器主管侧壁均匀分布着直径均为315 mm 的8 个小孔

主管中的气液混合物通过安装在主管外壁上的环室进入侧支管. 通过在空气O水实验台上 对水平管气液环状两相流通过该分配器进行的实验研究发现:与传统三通分配器的分配特性不同

该分配器的液相会优先进入侧支管. 建立了相分配模型

认为对于环状流

通过管壁小孔的液膜将 被小孔捕获

从而进入侧支管. 该模型还提出了分配影响区修正系数

实验发现该系数与入口干度 成线性关系. 预测的气液相分流系数、主管出口与直通管间压力损失与实验结果吻合得很好

最大 误差为7124 %.

Abstract

A new T2junction type dist ributor which is different f rom t he conventional T2junction was designed. The dist ributor was composed of eight small holes wit h a diameter of 3. 5 mm on t he pipe wall and a ring casing mounted out side of t hese holes. The gas2liquid mixt ure f rom t hese small holes will flow t hrough t he side arm of the dist ributor . Experiment s were conducted in a hori-ontal gas2liquid two2p hase loop to study t he split of annular flow. The result s show t hat t he liquid preferentially enters t he side arm. In comparison

gas is more easily diverted into the side arm for t raditional T2junction. A model was developed to predict t he flow split ting characteristics of hori-ontal air2water annular flow. The model was based on t he assumption t hat the liquid film passing t hrough t he small holes would be capt ured and enter the side arm eventually. Also t he coefficient of dist ribution influence -one in t he model is
