Abstract

In the present study, fluid flow and heat transfer in microchannel heat sinks with divergence microchannels using two nanofluids were numerically studied including the entire microchannel heat sink. The divergent channel has the cross-section of 100 x100 ?m2 at inlet and 560 x 100 ?m2 at exit. The pressure drop and thermal characteristics of heat sinks were investigated for Reynolds number varying from 50 to 250 and at constant heat flux. The effect of Reynolds number on Nusslet number and on pressure drop was studied. The results show that the volume fraction of nanoparticles and Reynolds number has major effect on microchannels heat transfer enhancement.
