Abstract: Nano-inclusions are thermally conductive particles that improve the thermal conductivity of liquid mediums. In this paper, the thermal properties of Mg2Si were evaluated after the addition of TiO2 nanoparticles. An instrument measured the thermal conductivity of the nanofluid using the transient plane source (TPS) method. Results showed that the thermal conductivity of the nanofluid was the highest at lower temperatures, and did not improve with the addition of the thermally conductive TiO2 nanoparticles.
