The effects due to fluid pH and dispersant concentration on the dynamic viscosity for the Al2O3–water and TiO2–water nanofluids had been experimentally investigated. The viscosity of the two kinds of nanofluids was measured using capillary viscometers. The experimental results showed that there exists an optimized value of pH (pH≈8.0) at which the viscosities of the two nanofluids take their minima values. The experimental results also showed that the influence of dispersant concentration on the viscosity of Al2O3–water suspension was relatively large comparing with that of the TiO2–water nanofluid, and the dispersion of alumina powder is poorer than that of titanium dioxide powder at the same pH value and same mass fraction.
