摘要: 提出了计算垂直上升弹状流中尾随Taylor气泡上升速度的关系式;并基于气泡追赶合并机理,建立了预测沿管路任意位置液弹长度分布模型,提供了弹状流发展过程中弹长分布的变化情况。

Abstract: Based on the relation between the trailing bubble velocity and the length of liquid slug ahead of that bubble obtained in the experiment, this paper presents a model that is able to calcukte the slug length distribution at any designated location along the tube. The results of the calculation is in agreement with the experimental data.
