Abstract
Based on an analysis of the physical mechanism, a new model is develop ed for the transitions for slug flow to churn flow in vertical pipes. The transition is attributed to the wake effect of Taylor bubbles on h ighly aerated liquid slugs. The new model is compared with existing mo dels and published experimental data. It is in better agreement with e xperimental data than existing models. (C) 1997 Elsevier Science Ltd.
