到目前为止，大多数研究T型接头处相分离的实验都是在直径大于约10 mm的管道中使用接近大气压的空气-水进行的。这里报告的研究已经研究了空气-水流的分裂，使用0.005米的T型接头，所有管道都在水平面上。相分离的分析仅限于弹状流状态下的四种气体表观速度，1.14，1.82，2.28，4.56m/s，和三种液体表观速度，0.093，0.166，0.313m/s。对于每次实验运行，T形接头处的压力保持在148 kPa。这补充了以前的研究进行了相同的钻机时，流动模式是环形或分层。利用高速摄像机获得了不同气液入口表观速度下弹状流的定性和定量结果。录像记录了充分发展的段塞流以及该流如何在T形接头处分开。段塞流的测量特性进行了比较，与以前公布的方法预测段塞流变量。
To date, the majority of all experiments investigating phase split at T-junctions have been conducted using air–water at near atmospheric pressures in pipes greater than about 10mm in diameter. The research reported here has studied the split of air–water flows using a 0.005m T-junction with all pipes in the horizontal plane. Analysis of the phase split has been confined to the slug flow regime for four gas superficial velocities, 1.14, 1.82, 2.28, 4.56m/s, and three liquid superficial velocities, 0.093, 0.166, 0.313m/s. For each experimental run the pressure at the T-junction was maintained at 148kPa. This compliments previous research conducted on the same rig when the flow pattern was annular or stratified. Qualitative and quantitative results of the slug flow under the differing gas and liquid inlet superficial velocities were obtained using a high-speed video. Footage was recorded of both the fully developed slug flow and how this flow divided at the T-junction. Measured properties of the slug flow were compared with previously published methods for predicting slug flow variables.
