Experimental study on the thermo-physical properties of diathermic oil based SiC nanofluids for high temperature applications

With the purpose of filling the research gap in the literatures, this paper presents experimental data of thermal conductivity and viscosity properties of DO-based SiC nanofluids. It was found that the thermal conductivity of nanofluids increased with the volume fraction, and the highest thermal conductivity enhancement was found to be 7.36% for 0.8 vol.% nanofluid at 50 °C. The prepared DO/SiC nanofluids behaved Newtonian behavior and the viscosities decreased with the increasing temperature. In addition, the overall effectiveness of nanofluids decreased with the increase of temperature, which indicated potential applications for energy systems in high temperature.
