【Abstract】 A long bubble rising in flowing liquid in a vertical tube is one of the most fundamentalphenomena of gas-liquid two-phase flow. An experimental study on this phenomenon is carried out. The non-invasive measurements of the gas-liquid flow field are obtained by usingthe EKTAPRO 1000 high speed motion analyzer. The rising velocity and the shape of longbubbles are investigated. The experimental data are compared with the existing practical ortheoretical correlations and a good agreement is obtained.更多还原
