This research work is an experimental study focusing on the thermophysical properties of water/EG based hybrid nanofluid suspended with CuO and Al2O3 nanoparticles. The main objective of the study is to investigate the effect of volume concentration and temperature on the thermal conductivity and dynamic viscosity of water/EG based hybrid nanofluid. The CuO-Al2O3 (50:50) nanoparticles were dispersed in the base fluid at a volume concentration between 0.25– 1.0%. The thermal conductivity and dynamic viscosity of the nanofluid were experimented with at a temperature ranging between 30–70°C. The hybrid nanofluid with 1% concentration of CuO-Al2O3 nanoparticles was found to be the most stable nanofluid with a zeta potential of -35.1 mV. Meanwhile, the increase in CuO-Al2O3 nanoparticle volume concentration increases the thermal conductivity of base fluid by almost 8.67% at a temperature of 70°C. The increase in volume concentration of nanoparticles increases the dynamic viscosity of the base fluid, while the increase in temperature significantly reduces the viscosity of CuO-Al2O3 hybrid nanofluid. The proposed nanofluid has good potential to be used in the convective heat transfer application. [ABSTRACT FROM AUTHOR] |
