Abstract: Nanofluids are heat transfer fluids with enhanced thermal conductivity properties due to the addition of metallic-based nanoparticles. In this study, the thermal properties of Al¬2O3 and TiO2 nanofluids were examined to evaluate their usefulness in microchannel heat sink applications. A thermal constants analyzer measured the thermal conductivity of the nanofluids using the transient plane source (TPS) method. Results showed that thermal conductivity increased with volume fraction of nanofluids, and the TiO2 nanofluids enhanced thermal conductivity more than the Al¬2O3 nanofluids.
