Research on nanofluids has developed rapidly in the application of its heat mechanism to a machine's performance. Heat mechanisms in nanofluids have emerged as promising fluid heat transfers, as for example in applications as a coolant in Thermal Photovoltaic. This study will discuss the effect of the Hybrid Copper Oxide/Titanium Dioxide (CuO/TiO2) Nanofluida on the rheological properties using based water. The purpose of this study was to determine the rheological properties and dynamic viscosity of the hybrid Copper Oxide/Titanium Dioxide (CuO/TiO2) nanofluids based-water performance on system. Hybrid nanoparticles were used to synthesize nanofluids using a volume ratio of 50:50 at 1L of water. Begin by mixing both of nanoparticles CuO and TiO2 with based-water using a magnetic stirrer at a speed of 650 rpm for 60 minutes, then followed by an ultrasonic stirrer for 1 hour so that the two nanoparticles become more homogeneous. The dynamic viscosity obtained using the NDJ-8S Viscometer uses variations in temperature of 20 OC, 30 OC, 40 OC, 50 OC, 60 OC with speeds of 6 rpm, 12 rpm, 18 rpm, 24 rpm, and 30 rpm. The results obtained in the form of viscosity, shear rate, and shear stress. © 2024 American Institute of Physics Inc.. All rights reserved.
