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.
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). … 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
