【 摘 要 】

In order to explore the characteristics of slug flow in horizontal curved tube, four kinds of curved tubes are researched in this paper of which are with 0.5m circumference, 26mm inner diameter. When the superficial liquid velocity or the superficial gas velocity increases, the probability distribution of the average velocity, average length and average frequency of liquid slug conform to the Gaussian distribution at all of the experimental conditions. The average velocity, average length and average frequency of liquid slug increase with the increase of superficial gas velocity. In addition, as the radius of curvature of the pipeline increases, the average velocity, average length, and average frequency of the fluid plug increase.
