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.

采用瞬态热线法测量纳米流体的导热系数，结果表明：纳米流体导热系数的变化与纳米颗粒体积分数和温度的变化成正比，其中25℃时体积分数为0.3%的SiO2-水纳米流体相对于水的导热系数提高11.5%，而在50℃时则提高46.5%。
