Abstract :

In this paper, we aim to investigate the dynamic viscosity of the Mg(OH)2-ethylene glycol(EG) nanofluid. The study is conducted in different solid volume fractions (0.1%, 0.2%, 0.4%, 0.8%, 1%, 1.5%, and 2%) at the temperatures of 23 and 55⁰C. It should also be mentioned that the average diameter of the nano-particle is 10nanometer. Moreover, the Newtonian behavior of the nanofluid is evidenced by examining the shear rate of the nanofluid. The results proof that while the solid volume fraction is increased, the dynamic viscosity is increased too. This increase is more noticeable at lower temperatures in comparison with higher temperatures.
