Experimental investigation of dynamic viscosity of MWCNT-CuO (20:80) hybrid nanofluid suspended in water

This paper focuses on dynamic viscosity of a new class ofnanofluids called hybrid nanofluids. The considered hybridnanofluid in this study was produced by dispersing bothCuO and MWCNT nanoparticles in de-ionized water. Theproperties of nanofluids are measured at different volumefractions (ranging between 0.05 and 1%) and varioustemperatures (25- 45oC). The results elucidate that hybridnanofluids with all concentrations behave as Newtonianliquids except volume concentration of 1%, the nanofluids isnon-Newtonian. It is also found that when the volumefraction increases from 0.05% to 1%, the viscosityexperiences a remarkable enhancement.
