โœฆ Synopsis

Based on an analysis of the physical mechanism, a new model is developed for the transitions for slug flow to churn flow in vertical pipes. The transition is attributed to the wake effect of Taylor bubbles on highly aerated liquid slugs. The new model is compared with existing models and published experimental data. It is in better agreement with experimental data than existing models.

An experimental study on the dispersed bubble to slug flow transition in a narrow tube is reported in this work. It shows that the superficial liquid velocity is an increasing function of the superficial gas velocity along the transition boundary. It also shows that the transition always occurs at a
