WebWith great momentum, the entrained droplets in the churn flow travel along the pipe into the annular flow and inevitably affect the downstream flow field. Thus, it is more reasonable to start the calculation from the transition of the slug to the churn flow rather than the annular flow. The usual practice was to assume the entrained fraction at ... WebChurn flow also referred to as froth flow, is a highly disturbed flow of two-phase fluid flow. The increasing velocity of a slug flow causes the structure of the flow to become unstable.

WebJun 15, 2024 · Churn flow has a similar character and occurs in a similar range of fluid mass flux changes as slug flow but at larger air mass flux. Fast flowing gas causes a loss of liquid continuity, which flows in the form of aerated portions with an irregular shape. Portions of this mixture flow through the channel at high speed, cyclically at intervals ... WebDec 1, 1999 · Two separate hydrodynamic models are presented to predict pressure drop and liquid holdup in churn flow.
