本文研究了具有主、侧分支直径为500μm的水平微三通内空气-水两相流的流动特性。当入口流型为段塞流-环状流时，详细研究了上游气液表观速度的变化对T型管内两相流相分布的影响。实验结果表明，随着液体表观速度的增加，脱液量减少，而随着气体表观速度的增加，脱液量增加。入口气速较高时，气液表观速度对相分布的影响较大。当本数据进行比较，从较大直径的T形接头在类似的入口表观速度，它被发现，减少T形接头的直径增加了液体的分数。
The behavior of air–water two-phase flow at a horizontal micro-T-junction with main and side branch of 500μm diameter was studied in this work. When the inlet flow pattern was a slug–annular flow, the impact of varying of upstream gas and liquid superficial velocity on phase distribution of two-phase flow in the T-junction was investigated in detail. It is found that the liquid taken off decreases as an increase in liquid superficial velocity, while it increases as an increase in gas superficial velocity. Liquid and gas superficial velocity have stronger impact on phase distribution when the inlet gas velocity is high. When the present data are compared to those from larger diameter T-junctions at similar inlet superficial velocities, it is found that decreasing the diameter of T-junctions increases the fraction of liquid taken off.
