文章应用DPIV方法对气液两相流在管道中不同位置分布情况进行了计算，分别从不同流型，不同气相流量两种情况下对轴向平均速度、轴向速度均方根、径向速度均方根以及雷诺应力四个参数进行计算分析，通过不同角度计算分析，得到结论：气液两相界面波对流动影响较大，气泡分布散落状态对流动影响较大，雷诺应力在相界面与管壁附近有明显峰值。
The paper computed the distribution of different position of gas-liquid two-phase flow pipe based on the DPIV method. And calculated the four parameters （axial average speed, axial speed mean square root, radial velocity mean square root and Reynolds stress） from the different flow pattern and different gas phase flow. The conclusion is that： the flow are influenced mainly by the wave of the interface of gas-liquid two phase and the distribution state of bubbles. Reynolds stress have an obvious peak in the interface and the near wall.
