柱塞流的统计分析

The Statisical Analysis on Slug Flow

通过对气液混合输送管道中柱塞流的测量结果进行统计分析,得到了气液混合输送中柱塞流的一些运动规律,并且发现柱塞流在实验室小管径管道的运动规律与实际大管径管道的运动规律不同,在柱塞流稳定的状态下,气腔的长度变化与柱塞和气腔的速度差密切相关。

The results of statistical analysis on slug flow have been obtained in an actual gas-oil pipeline,also some relations between slug and bubbles movement parameters with the correlation analysis for experiment of data;and some of them are different with the results obtained in small pipe under the laboratory conditions. There is stronger correlation relationship between the head velocity of slug flow and tail velocity of that which is contrary to the conclusions obtained under the laboratory.
