Experiments have been conducted to measure the dynamic viscosity and thermal conductivity of aluminum oxide (Al2O3) nanoparticle dispersions at 6% vol. in liquid water. Rheological characterization of the Al2O3–water nanofluid has shown that it exhibits a Newtonian fluid behavior for the shear rate range of 6 to 122 s−1 between 6 and 75°C. Measurements of the nanofluid thermal conductivity have been performed for temperatures between 7 and 55°C, and have been found to be 8 to 17% higher than that of water. Thermal conductivity of the nanofluid responded to temperature increase with appreciation in value. When compared with correlations available in the literature, the measured thermal conductivities are in better agreement with correlation that includes the effect of temperature.
