title: Thermal performance of higher aspect ratio microchannels using TiO2-water nanofluids.
abstract: An experimental setup was developed to study the heat transfer and fluid flow characteristics in rectangular copper microchannels with hydraulic diameter 29.4 microm using TiO2-Water nanofluids. The experimental facility is validated using existing correlations and subsequently tested with 0.1% and 0.3% concentrations of TiO2 nanofluids. The thermal resistance of heat sink with nanofluids is compared with the base fluid. It is inferred that 0.3% TiO2-Water nanofluids have 18% lower thermal resistance as compared to base fluid having for the same operating conditions.
