Abstract :

In the present study, the thermal conductivity of Mg(OH)2-EG nanofluid has been experimentally investigated. All the experiments have been carried out at the temperatures ranging from 24 to 55 °C and different solid concentrations (0.1, 0.2, 0.4, 0.8, 1, 1.5, and 2%). The results declared that the variations of thermal conductivity of Mg(OH)2-EG nanofluid with respect to temperature at the solid volume fractions less than 0.4 %, compared to the higher solid volume fractions, is negligible. Furthermore, the maximum and minimum percentage of increasing the thermal conductivity at solid concentration of 2% is 22% at 55°C and 13% at 24°C, respectively.
