摘要：

The paper presents the results of measurements of rheological properties of ethylene glycol (EG) based aluminum oxide (Al2O3) nanofluids. The nanofluids have been produced by two-step method with the use of commercially available nanoparticles. Dynamic viscosity curves and dependence of viscosity on temperature for these materials have been measured. It has shown that with higher concentration of nanoparticles in the suspension, these nanofluids exhibit the non-Newtonian flow and it can be considered as shear-thinning liquids. The effect of temperature on the dynamic viscosity in Al2O3 EG nanofluids can be modelled with the use of Vogel Fulcher Tammann expression.
