- When the liquid superficial velocity was relatively high, with increasing mixture velocity, the chaos of liquid slug length fluctuation would increase. 液相折算速度较大时,随着混合速度的增加,液塞长度波动的混沌程度增加;
- On the condition of a larger pipe inclination angle, the distribution of liquid slug lengths was more concentrated in a smaller range. 在管线下倾角较大的情况下,液塞长度分布集中在较小的范围内。
- A region with high local concentration of dispersed bubbles is formed in the front of the liquid slug, because the liquid film entrains gas penetrating the liquid slug. 并在液弹空隙度预测中引入临界气体夹带速度的概念,以此来描述弹状流中大气泡尾部的混合特性。
- In this paper,the characteristics of slug velocity during the four stages of severe slugging in the pipeline-riser system were studied. 结果表明:在液塞形成阶段,液塞速度随气液相折算速度的增大而线性增大;
- By reducing intermittency to periodicity, the very complex slug flow structure is simplified to an equivalent unit consisting of a liquid slug, one adjacent Taylor bubble and an aerated liquid film. 基于等效弹单元思想,改进了预测垂直上升管中充分发展气液弹状流流动特性的模型。模型中考虑了界面切应力对液膜运动的影响;
- The method of predicting liquid holdup in liquid slug was determined according to experimental data,and correlation experimental data from literatures were used to evaluate the model. 经对比分析认为,所提出的压力梯度计算方法不仅涉及的中间参量少、计算简便,而且对不同来源的数据适应性好、计算精度高。

- Also this method could reduce the maximum pressure of the system and prevent the occurrence of the high frequency slug flow with long liquid slugs in the upstream horizontal pipeline. 在模拟集输-上升管路系统的实验装置上,对消除严重段塞流现象的气举法进行了实验研究。
- All these not only avoid accumulating too much oil into the cylinder and inducing the liquid slugging, but also solve the worse cooling effect of the sole external cooling. 这样既避免了汽缸中积存过量的油导致液击,也解决了只对汽缸进行外冷却时冷却效果不佳的问题。
- Slug liquid holdup would change with the gas or liquid superficial velocity. 利用这一特征可初步确定段塞流动中气、液相流量相对大小。
