An experimental investigation has been made into the pressure/flow behaviour of a collapsible tube subjected to downstream pressure fluctuations. These downstream pressure waves are observed to be transmitted upstream beyond the point of collapse. The mean flow rate is not significantly affected by the amplitude or frequency of pressure fluctuations. However, the oscillatory flow amplitude is reduced at the higher frequency. The mean flow rate also remains independent of the mean driving pressure.
针对承受下游压力波动的可塌陷管道的压力/流量行为进行了一项实验研究。观察到这些下游压力波会向上游传播至塌陷点之外。平均流速受压力波动的幅度或频率影响不显著。然而，在较高频率下振荡流幅度会减小。平均流速也与平均驱动压力无关。
