【摘要】 采用瞬态热线法测量了4种不同种类、不同体积份额配比的纳米流体的导热系数,分析了纳米颗粒属性、体积分数、悬浮稳定性及温度等因素对纳米流体导热系数的影响。实验结果表明,在流体中加入纳米颗粒将显著提高流体的导热系数。更多还原

【Abstract】 The transient hot-wire method is used to measure thermal conductivities of four kinds of nanofluids. Thermal conductivities of nanofluids are not only influenced by volume fraction of nanoparticles, but also by other factors such as. properties and suspending stability of nanoparticles and temperature. The experimental results show that nanofluids have substantially higher thermal conductivities than the same liquids without nanoparticles.更多还原
