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. WebThe flow regime is dependent on : the fluid velocity, the pipe diameter, the volumetric mass of the fluid and the viscosity of the fluid. Higher velocity will tend to make the flow more …

WebCalculating flowrate through long, straight pipe under laminar flow regime is easy using standard equations of fluid mechanics. Real piping systems, as it is known, usually … WebSlug flow is a destructive, intermittent multiphase flow pattern that has a sequence of elongated bubbles followed by a segment of liquid below the bubble bottom. The hydrodynamics of the slug flow pattern are the most prevalent and complex flow patterns, and the intermittency can cause instabilities in systems where it forms. how to spell baje

WebApr 10, 2024 · Although these states have been observed at flow regimes around laminar–turbulent transition (Re ≈ 2300) and also at high Reynolds number pipe flow (Re ≈ 35 000), at moderate Reynolds numbers, their existence had not been observed yet by experiment. By conditionally averaging the flow fields with respect to their dominant … 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.
