文摘
- •
The effect of temperature and particle concentration on the viscosity is studied.
- •
Experimental data of dynamic viscosity of ZnO–EG is compared with the existing models.
- •
Two empirical correlations are proposed to estimate the dynamic viscosity of ZnO–EG nanofluid.
- •
At a fixed concentration, with increasing temperature, the viscosity of the fluid is not seen significant change.
- •
Experimental data in an excellent agreement with correlations which have been presented in this investigation.
