An Experimental Determination of the Flow Pattern for a Gas-Liquid Two-Phase System in Vertical Pipes |

Abstract |

内容記述 |
A gas-liquid two-phase system was experimentally studied for the case that gas(air) was supplied, through a disk with multiple holes, from the bottom end of a vertical pipe into the initally stagnant liquid (water) column with a free surface. The behavior of the two-phase mixture in the stagnant liquid column was observed visually and the flow pattern was determined using measured void fractions. In a range of low air flow rate where the flow pattern is always a bubbly flow, the void fractions at the pipe center have constant values of less than 0.2. With an increase in air flow rate, the flow state becomes unstable at lower part of the pipe; whereas, for the higher part of the pipe, the flow pattern turns to either transition or slug flow, depending on the vertical position. And the void fraction at the pipe center decreases sharply along the pipe axis for the transition flow and has a constant value between 0.3 and 0.4 for the slug flow. |
