Flow regime in pipe
WebNov 17, 2024 · Annular -Mist Flow: During annular, the liquid phase flows regularly as an annular film on the wall with gas flowing as a central core. Some of this liquid is entrained as droplets in this gas core (mist flow). … WebApr 6, 2024 · The FIV response and flow pattern evolution are examined with a gas flow rate of Qg = 4–12 kg/s and a liquid flow rate of QL = 96–288 kg/s. When the gas–liquid flow passes through the jumper, the flow regime subsequently presents the slug flow, bubble flow, churn flow and imperfect annular flow.

Web摘要： The objective of this work is to study the heat transfer characteristics and predict the flow pattern of an oscillating heat pipe (OHP). In the present study, two-dimensional OHP and three-dimensional OHP were designed and the temperature oscillations of the OHPs were experimentally studied for applications in electronics cooling conditions. WebJan 19, 2024 · Three flow patterns are obtained in the present work, which is bubbly, slug, and annular flows. The Probability Density Functions of the cross-sectional void fraction …
WebAt laminar regime of flow the velocity is highest on the pipe axis, and on the wall the velocity is equal to zero. When the velocity is greater than "critical", the regime of flow is … When a fluid is flowing in the laminar regime, its flow behavior is very easy to visualize and understand. Flow is driven entirely by external forces, which are usually just gravity and the driving pressure. Laminar flow is sometimes characterized as only occurring in incompressible inviscid fluids—this is incorrect. The … See more The turbulent flow regime is at the other end of the flow spectrum corresponding to very fast flow rates. Turbulence is one of the most … See more There is a region of Reynold number values called a transition region, wherein the flow behavior begins to change from laminar to turbulent. This should underscore that there is no sharp dividing line between the … See more
