Experimental study of the thermal conductivity features of the water based Fe 3 O 4 /CuO nanofluid

The properties of thermal conductivity of water based Fe 3 O 4 /CuO nanofluid with respect to different parameters such as temperature and weight percent of forming nanoparticles were empirically investigated. The thermal conductivity was measured using hot wire method. According to the results, the thermal conductivity of the Fe 3 O 4 nanofluid in the presence of different concentrations of CuO nanoparticles increases significantly. A linear relationship between increasing the concentrations of CuO nanoparticles and the growth of thermal conductivity of Fe 3 O 4 nanofluid in the temperature range of 25 to 50 °C was observed.
