摘要
运用瞬态热线法测定了不同种类、不同体积份额配比的纳米流体的热导率 ,分析了纳米粒子属性、份额、尺度等因素对纳米流体热导率的影响 .实验结果表明 ,在液体中添加纳米粒子显著增加了液体的热导率 .通过对实验结果进行分析 。
The transient hot-wire method is used to measure the thermal conductivities of nanofluids.The experimental results show that nanofluids have remarkably higher thermal conductivities than those of conventional pure fluids.The thermal conductivities of nanofluids are not only influenced by the volume fraction of nanoparticles, but also by other factors such as properties and dimensions of nanoparticles.By analyzing the experimental results, a correlation of thermal conductivity of nanofluid is presented.
