摘要 介绍了运用瞬态热线法测定不同体积份额、不同温度下水-氧化铜纳米流体的热导率。实验结果表明纳米流体较传统的纯液体具有较高的热导率;体积份额、温度对纳米流体热导率具有一定的影响;温度对纳米流体热导率影响的显著程度与纳米粒子体积份额有密切关系。 The transient hot wire method is used to measure the thermal conductivities of CuO nanofluids at the different ovlume fraction and temperature.The experimental results show that nanofluids have remarkably higher thermal conductivities than those of conventional pure fluids,the thermal conductivities of nanofluids are influenced by the volume fraction of nanoparticles and temperature and the effect degree of temperature on the thermal conductivities of nanofluids is associated with the volume fraction of nanoparticles.
