本文对气液两相泡状流向弹状流转换的机制进行了分析,认为气泡合并是影响该流型转换的主要机制,并据此用随机数值模拟方法,对气泡初始尺寸对泡状流向弹状流转换的影响进行了研究.计算结果表明,无量纲气泡碰撞率是一条通用曲线,根据该曲线可以确定气泡初始尺寸产生影响的区域及其大小,与实验结果的比较令人满意. |

In the present paper, common accepted mechanisms for the bubble-to-slug transition (BST) of two-phase gas-liquid flows are reviewed. It is shown that BST will be controlled by the bubble coalescence. A random numerical method is used to simulate the influence of the initial bubble size on the bubble-to-slug transition based on the bubble coalescence mechanism. It is found that the locus of the dimensionless rate of collision is a universal curve. Based on this curve, the range and the intensity of the influence of the bubble initial size on the bubble-to-slug transition are determined, which agrees very well with the experimental data. |
