RESUMO

The present study presents and overview of the reported work on gas-liquid churn flow, and attempts to elucidate the important physical phenomena and mechanisms associated with it. The following features of this flow pattern have been addressed: mechanisms and models for the slug-to-churn flow transition; transition from churn to annular flow; prevalence of churn flow at high liquid flow rates; churn flow in inclined tubes; and prediction of pressure drop and holdup characteristics. It is concluded that although churn flow has a complex and chaotic nature, some basic mechanisms of the flow can be identified which provide the framework for a relatively ordered view (and lines of study) of the flow pattern.
Procedures have been outlined to calculate when the flow regime would occur, and what the pressure drop and the holdup would then be. However, these design recommendations have been developed using air-water data, and their extension to other fluid systems and geometries should be investigated.
