摘要

提出一种新的气液两相流体等干度分配方法——分相分配法.该方法的特点在于

基于单相流体较容易实现均匀分配的特征

首先通过强化两相流体在分配单元内的相分离

将气液混合物分离成单相或接近单相的气体和液体

然后以单相流的形式分别进行分配

最后将分配后的单相气、液进行两两汇合

完成两相流体的等干度分配.在空气-水实验回路上对这种分配方法进行了实验研究

结果表明

在分层流、波状分层流、弹状流和部分环状流的情况下

气液两相流体均能在分配元件内得到较好分离

保证在单相或接近单相的状态下进行分配

支路与主路间的平均干度偏差小于1.6%.

Abstract

A new method for gas-liquid two-phase flow distribution

the phase separation method

was proposed. This method can convert two-phase flow distribution into single-phase feed in the distribution process of two-phase flow

and ensure an equal quality distribution. First

the mixture of gas and liquid is separated into single or near single phase fluids by enhancing phase splitting in a distributor. Second

the single gas and liquid flow are fed as required with liquid and gas mass flow rate meters

respectively. Third

each couple of gas stream and liquid stream is recombined in a branch. Experiments were conducted in an air-water multiphase flow test loop. The flow patterns in the experiments included stratified flow

wavy flow

slug flow and a part of annular flow. The experimental results show that the present phase separation method and apparatus could be feasible to complete equal quality distribution and the deviation of stream quality in different branches was less than 1.6%.
