Abstract:
The study focused on the impact of concentration and temperature on the electrical conductivity,
viscosity, and thermal conductivity of GNP/Fe2O3 hybrid nanofluids. The study found that
nanofluids have better electrical conductivity, viscosity, and thermal conductivity than water. The
electrical conductivity and thermal conductivity increase linearly with concentration for a constant
temperature. However, the nanofluid’s viscosity increases with the addition of the hybrid nanoparticles
and decreases as the temperature increases. Furthermore, the study shows that the thermal
conductivity of the nanofluid is enhanced with increased addition of hybrid nanoparticles in the
base fluid and that the thermal conductivity ratio increases with increased addition of nanoparticles.
Overall, the results suggest that GNP/Fe2O3 hybrid nanofluids could be used in various industrial
applications to improve the heat transfer and energy efficiency of systems.
