This paper presents an experimental investigation of rheological and thermal transfer properties of A1₂O₃ nanoparticles suspended in 45:55 (by volume) ethylene glycol and water mixture. The linear relation between shear stress and shear rate at the same temperature shows that the A12O3 nanofluid exhibits Newtonian behavior. The viscosity of nanofluid considerably increases with the enhancement of particle volume fraction, and decreases with increasing temperature from 10 ◻ to 60 ◻. The enhanced thermal conductivity ratios of the nanofluids with the volume fraction 1% and 3% were measured. The results show that the absolute thermal conductivities increase with...
