Data: Two-phase Gas-Liquid Flow Regimes Identification in an S-shape Pipeline-Riser Using Doppler Ultrasonic Sensor

Different flow regime data was generated experimentally at Cranfield University using a 2-inch multi-phase flow S-shape pipeline-riser test loop. In order to obtain the desired flow regime condition, the air-water flow rate was automatically regulated using the DeltaV system. Allfiles.Mat contains all the Air (Sm3/hr) - Water (Kg/s) flow regime conditions investigated. The data was recorded using the LabVIEW program but converted to a MATLAB file for easy access. All the flow conditions that fall under category 1 are in slugging condition, all that fall into category 2 are in bubbly condition, the ones that fall under category 3 are in churn flow condition and the ones that fall under category 4 are in annular flow condition. Data_wave2.mat is also a MATLAB file that contains all the flow conditions investigated. It contains the same data as in Allfiles.mat. You can use either Data_wave2.mat or Allfiles.mat files. <br> <br>

本数据集的多流态实验数据由克兰菲尔德大学（Cranfield University）通过2英寸多相流S型管道-立管试验回路实验生成。为获取目标流态工况，研究人员通过DeltaV系统对气-水流量实现自动调节。Allfiles.mat收录了本次研究涉及的全部气（Sm3/hr）-水（Kg/s）流态工况组合。实验数据通过LabVIEW程序采集记录，并转换为MATLAB格式文件以方便调用。

其中，类别1对应段塞流工况，类别2对应泡状流工况，类别3对应搅混流（churn flow）工况，类别4对应环状流工况。Data_wave2.mat同样为MATLAB格式文件，包含与Allfiles.mat完全一致的全部流态工况数据，二者可任选其一使用。
