Abstract

Researchers have been looking at heat exchange systems as of late to determine which is the most dependable and effective. In comparison to traditional heat transfer fluids, the characteristics of high-performance ultramodern nanofluids are far superior. Because of its impact on the pumping needs of thermal systems, understanding the viscosity of nanofluids is crucial. Concentration and temperature effects on the dynamic viscosity of graphene (Gr) and titanium carbide (TiC) nanofluids are investigated. To synthesize nanofluids with a concentration of volume of 1% to 7%, we first dispersed Gr nanoparticles in ethylene glycol (E), then TiC in E, and finally TiC in distilled water (W), using the two-step procedure. The viscosity of these nanofluids was measured experimentally with an Ostwald viscometer between 25 and 65 °C. A correlation between nanoparticle concentration in volume and the measured nanofluids’ viscosity was found. The viscosity ratio of TiC nanofluids was 1.145 and 1.712 times that of the base fluid at 1 and 7% volume concentration. In addition, raising the temperature above that of the basic fluids causes the nanofluids to become less viscous.
