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 turbulent flow is a two-phase gas/liquid flow regime characterized by a highly-agitated flow where gas bubbles are sufficient in numbers to both interact with each … 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. The churn flow is characterized by a …
WebJan 5, 2024 · Numerical simulations of evolution characteristics of slug flow across a 90° pipe bend have been carried out to study the fluid—structure interaction response induced by internal slug flow. The two-phase flow patterns and turbulence were modelled by using the volume of fluid (VOF) model and the Realizable k−ε turbulence model respectively. …
