Determining Slug Velocity and Slug Length of Slug Flow in Horizontal Pipe Using Crossing-correlation Method of Differential Pressure Signal

    摘要
  • 摘要: 分析了差压信号和波高信号之间的对应关系, 给出了利用差压信号求液塞速度的方法。提出了“假渡越时间”的新概念, 根据这一概念给出了求液塞长度的方法, 试验结果表明, 该方法是求解液塞长度比较有效的一种方法。

     

    Abstract: This article analyzes the corresponding relationship between differential pressure signal and wave-height signal, and gets velocity of liquid slug using cross-correlation method of differential pressure signal. It also gives a new conception named "pseudo-transition time", and gives a new method to get length of liquid slug. The experimental data show that this new method is an efficient one to get length of liquid slug.
