Experimental investigation of effective parameters on MWCNT–TiO2/SAE50 hybrid nanofluid viscosity
In the present study, rheological behavior of multi-walled carbon nanotube (MWCNT) (30%)–TiO 2 (70%)/SAE50 hybrid nanofluid is investigated. Samples of nanofluid with nanoparticle concentrations of 0% up to 1% were prepared, and their dynamic viscosity was measured at temperatures between 25 and 50...
