垂直上升管内未充分发展弹状流流动特征参数的研究

Investigation of Characteristic Parameters on Under-developed Slug Flow in a Vertical Tube

采用电导原理对气-液两相弹状流中的弹状气泡速度、液塞速度、弹状气泡长度和液塞长度进行了测量。得到了各自随表观气速或表观液速的变化规律。并对弹状气泡长度进行了统计分析,结果表明:弹状气泡长度在显著性水平α=0.05的条件下符合正态分布。

This paper focuses on the measurements of the Taylor bubble and liquid slug velocity, and the length of the Taylor bubble and liquid slug by conductivity technology in a vertical short tube. The results show some regular patterns with the variation of the superficial gas or liquid velocity. And through the statistical analysis on the length of lots of the Taylor bubbles, the probability distribution of the length of the Taylor bubbles is subjected to normal school under the condition of α=0.05.
