| Abstract: | 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 a =0.05. |
