摘要
This paper reports an experimental work on the measurements of thermal conductivity and viscosity of Al2O3-water and Al2O3-ethylene glycol nanofluids. Results show that thermal conductivity values are within the limits of Maxwell model while viscosity increases dramatically with increasing particle concentration and decreases with increasing temperature. However, the relative viscosity is independent of temperature. Also pH, particle size and zeta potential of nanofluid samples are characterized.
