... height, as the aspect ratio increases, channel width decreases, and it is found that opportunities for agitation are reduced and the generated turbulence is more strongly damped, thus reducing heat transfer coefficients. A study was carried out to find direction toward an optimal number of channels...

... 23 02 2010 Experiments are conducted with a perfluorinated dielectric fluid, Fluorinert FC-77, to investigate the effects of channel width, depth, and aspect ratio on flow boiling heat transfer and flow patterns in microchannels. Experiments are performed for a fixed mass flux of 630...

... spreading of cooling liquid in the evaporator chamber. Experimental results had demonstrated that a greatest flow velocity of 206.9 mm/s could be obtained at a situation for rib width was 5 μm and aspect ratio was 15. Spreading time was increased gradually as increase at the depth of the rib. On the other...
