Studies on Thermal Conductivity and Zeta Potential of Cuo-Nanofluids at Different Temperatures
Keywords:
CuO Nanofluids, Thermal Conductivity, Tri-Ethylene GlycolAbstract
The purpose of the present investigation is to study the effect of adding copper oxide nano powder to the conventional heat transfer fluids for their comparative thermal conductivity properties. CuO nano powder was synthesized and subsequently different nanofluids were prepared in two base fluids such as water and tri-ethylene glycol by ultrasonication technique. Synthesized CuO nano powder was characterized for its shape and size from XRD, EDX and SEM analysis. Thermal properties of prepared nanofluids have been studied from thermal conductivity at different temperature. In addition, particle size analysis, zeta potential studies, viscosity and density of the nanofluids were carried out. The thermal conductivities of all nanofluids were found to be enhanced, whereas the density and viscosities of nanofluids were less in comparison to their base fluids.
