Heat transfer enhancement of staggered water-droplet grooved microchannel heat sink using Al2O3 nanofluid

ABSTRACT
The performance reliability and durability of modern cutting-edge technology are highly dependent on the ability of the devices to dissipate enormous amounts of heat to the ambient environment. A synergetic combination of two passive heat transfer enhancement techniques would be favourable to prevent overheating. The concurrent implementation of Al2O3 nanofluid and staggered water-droplet groove geometries in microchannel heat sink application was investigated using numerical approach. Numerical results reported in this study revealed that the heat dissipation capability of the microchannel heat sink can be improved when Al2O3 nanofluid is used in conjunction with the water-droplet grooves arranged in staggered manner. The predictive accuracy of the numerical method has been validated with published results available.
