چکیده

In this study, the rheological behavior of ethylene glycol (EG)-graphene nanosheet nanofluid is examined experimentally. The impacts of mass concentration of nanoparticles (0–5%), temperature (5–65 °C) and shear rate (0–90 ) on the dynamic viscosity of EG-graphene nanofluid are examined. The obtained results showed that incorporating graphene nanoparticles into EG causes fluid behavior to change from Newtonian to power-law non-Newtonian. In addition, it was found that the dynamic viscosity of EG-graphene nanofluid augments by boosting nanoparticle concentration and decreasing temperature. Moreover, the regression technique is utilized to develop predictive correlations of consistency-index and power-law index of the power-law model. The results demonstrated that the R-squared value for the obtained correlations for consistency index and power-law index are 0.925and 0.982, respectively.
