Thermal conductivity is measured by the transient hot-wire method, which shows that the thermal conductivity increases with the increase of nanofluid particle volume fraction and temperature. The thermal conductivity of 0.3vol% SiO2-water nanofluid increases by 11.5% at 25℃, while it increases by 46.5% at 50℃ when compared with water at the same temperatures.
