【摘要】 采用差压法对起伏管线中的多相流液弹长度进行了实验测量和分析,通过对实验数据的统计分析发现,液弹长度按正态分布规律分布,在上升段液弹长度比水平段液弹长度有所减小,而在下降段,液弹长度又会有所恢复。液弹长度的减小和增加会相应地造成液弹速度的增加和减小。更多还原

【Abstract】 The liquid slug length is measured in hilly terrain pipeline by difference pressure method. It is distributed according to normal law. It is shorter in upward section than that in horizontal section, then recovers slightly in downward section. The change of the liquid slug length leads to the change of the liquid slug velocity at the same time.更多还原
