Abstract

In this paper we report fluid flow characteristics of $AL_2O_3$ nanoparicles suspended in water. Especially, the effects of volume fraction with the range of 0.01% to 0.3% and inner diameter of tubes on the pressure drop and the effective viscosity of $AL_2O_3$ nanoparicles suspended in water are experimentally investigated. Experimental results are compared with analytic solution which can be derived with Einstein model. We confirm whether Einstein model which have been used to determine the effective viscosity of nanofluids is valid or not.
