文丘里式气泡发生器内气泡输运过程研究
Investigation of Bubble Transportation in Venturi-type Bubble Generator
摘要
Abstract
The visualized study was carried out involving the transportation and breakup process in a Venturi-type bubble generator.The air and water were used as working fluids with volumetric flow rates of 15-20 m3/h and 0.6-0.7 L/min,respectively in experiment,resulting in a void fraction in the range of 0.2%-0.3%.The results show that being different from that of a conventional channel,bubbles are decelerated rapidly after flowing out of the throat for Venturi tube,leading to a larger difference of velocities between the gas and liquid.This must have a significant effect on the deformation and breakup of bubbles.The water flow rate has little effect on the position of bubble breakup which is always at a distance from the throat about 8-10 mm and near the boundary between the vortex region and main stream.关键词
