水平并联管系统中两相流流量分配的理论及实验研究

STUDY ON THE GAS-LIQUID TWO-PHASE FLOW DISTRIBUTION CHARACTERISTICS OF A HORIZONTAL PARALLEL TUBE SYSTEM

在空气－水两相流试验台上，对水平放置集箱的Ｕ型和Ｚ型并联管系统中的两相流流量分配特性进行了理论和实验研究．着重对水平并联管中两相流流量分配规律进行了理论上的分析和推导，得到了计算各支管流量的计算式，并用实验进行验证，其计算结果和实验结果符合较好．研究结果对两相流并联管束的工程设计具有重要的参考价值．

In this paper, an experimental study on gas-liquid two-phase flow distribution characteristics in horizontal parallel tubes of a U-type and Z-type header system is conducted in anair-water test loop. On the basis of theoretical analysis, the computer program for calculating the two-phase flow rate distribution among parallel tubes is developed. The. calculatedresults are in good agreement with the experimental data.
