| 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. |
