Numerical Investigation of Cryogenic Two-Phase Flow Geysering Phenomenon in Vertical Tube
Abstract: The geysering phenomenon at different conditions in the vertical pipe is studied by CFD simulation. The results show that the slug bubble changes into the lump bubble and moves to the top level when it moves into the pool. When the bubble overflows the top level, the liquid droplet is splashed, and the liquid level changes periodically. The length characteristics of slug bubble are performed in cryogenic vertical geysering phenomenon. The geysering cannot be occurred when the length of slug bubble is too small. With the length of slug bubble is increased, the intensity of geysers is huger. The pressure frequency and intensity are increased when the number of Taylor bubble is increased.
