... of desktop CPU cooler. A computational domain from the whole cooler is selected, taking advantage of symmetry. With Reynolds number and temperature ranging from 100 to 2000 and 35°C to 95°C, a conjugate heat transfer analysis on the grid-independent domain brings out the Nusselt number as a function...

... that affects the heat rate at those boundaries and is rarely available in the literature. Depending on the location of heat pipes for a certain Reynolds number, the heat rate could be as high as 3.75% more than the heat rate due to their original locations. A high heat rate indicates an increase in heat...

... Abstract With the advent of Micro Aerial Vehicles (MAVs) and their widespread applications, the use of flat plate as a lift generation device has drawn utmost attention, and therefore, it needs to be investigated further. Usually, fixed wing MAVs work in the range of Reynolds number, Re = 10 4...

Further, the influence of nozzle exit to impingement plate distance (z/d = 2 to 6) is studied for different cross flow velocity to the main jet velocity ratios (M = 0 to 1). The Reynolds number (Re) is varied from 5000 to 50000. Furthermore...

... are considered in this work (z/b = 14 to z/b = 40), and two different Reynolds numbers are used Re = 11,000 y Re = 22,000. Three turbulence models are within reasonable accuracy (10%) of the experimental data, but some turbulence models have problems with convergence and grid independence, especially the URANS...

... with a wall thickness of 6.35 mm. Tests were conducted for Reynolds numbers ranging from 10 5 to 10 6 . Enhancement in heat transfer coefficient at all Re was recorded. The maximum heat transfer coefficient enhancement recorded was 86% at Re = 4.18×10 5 . Fuel rod Pressurized water reactor (PWR...

The results are obtained by analytical analysis, and some illustrations are dealt with in the paper, which clearly determine the importance of this factor of optimal fin length.

The parameters that affect the flow inside and around the test channel were the gap (g) between the obstruction geometry and the test channel, the Reynolds number and the length of the test channel. The maximum reverse flow inside the test channel observed was 20%–25% of the outside test channel...
