| 摘 要： | 本文对水平-S型柔性立管中空气-水两相流进行了实验研究,着重对各种流型下的立管底部压力信号进行了特征分析,给出了立管底部压力的变化速率、振幅谱特性以及分布律规律.分析结果表明,从严重段塞流到稳态流型,立管底部压力变化速率变化更加剧烈且频繁;压力波动频率增大且周期性减弱,波动模式复杂;压力分布律峰值从较高压力区域移向较低...

| Abstract: | An experiment is carried out in S-shaped riser system for gas-water two-phase flow in this paper.The key signal feature of the pressure at riser base including the change rate,amplitude spectrum and distribution of the pressure at riser base is analyzed to study the main characteristic of the flow.Some interesting results are obtained as follows.As the flow pattern changes from severe slugging to steady state,the change rate of the pressure at riser base becomes more frequently but not abruptly.The main fre... |
