A nanofluid is a generally considered to be base fluid that contains nanoparticle suspensions, where the nanoparticles could either be metals, metal oxides, or non-metals. Rheological properties of nanofluids play an important role in determining heat transfer capacity and pumping power of a fluid as they have the potential to improve heat transfer capacity and pumping power over a base fluid. This research can give us a clear understanding of how particle concentration and type of nanoparticle affect the viscosity of a nanofluid, which is the main parameter that influences the rheological properties of a fluid based on range of shear rates for various concentrations. Nanoparticles used for the experimentation are Al2O3 (5 nm) and TiO2 (5 nm) with paraffin oil (white, CAS No: 8020-83-5) as the base fluid. Nanofluids containing single and mixture of nanoparticles at 0.2--1.5 % volumetric concentrations are prepared using two step method with a sonication time of 12 hours and viscosity is measured using Brookfield Dv2T rotational viscometer with a cone (CPA-40Z) and plate apparatus. Results show that the Newtonian behavior exhibited by the base fluid changes to a non-Newtonian shear thinning behavior upon addition of nanoparticles and the viscosity increases with increasing the particle concentration. Viscosity of Al2O3 nanofluids was higher than the viscosity of TiO2 nanofluids and the viscosity of hybrid nanofluids was lower than Al2O3 nanofluids but higher than TiO2 nanofluids at lower concentrations, this trend follows up to 0.5% volumetric concentration but deviates for higher concentrations such as 1% and 1.5%.
