我们采用化学溶液法合成了Cu2O纳米流体：Cu2O纳米粒子悬浮液，并实验研究了反应物摩尔浓度和纳米流体温度对导热系数的影响。利用合成的纳米流体，可使导电率显著提高24%。通过调整一些合成参数，可以改变纳米粒子的形状。导热系数对反应物摩尔浓度和纳米流体温度表现出敏感性和非线性。(C)2009爱思唯尔有限公司。保留所有权利。
We apply the chemical solution method to synthesize Cu2O nanofluids: suspensions of cuprous-oxide (Cu2O) nanoparticles in water, and experimentally study the effect of reactant molar concentration and nanofluid temperature on the thermal conductivity. Substantial conductivity enhancement up to 24% is achievable with the synthesized nanofluids. The nanoparticle shape is variable by adjusting some synthesis parameters. The thermal conductivity shows both sensitivity and nonlinearity to the reactant molar concentration and the nanofluid temperature. (C) 2009 Elsevier Ltd. All rights reserved.
