Experiments were performed on the preparation and characterization of CuO-propylene glycol nanofluids. The influence of nanoparticle concentration and temperature on nanofluid viscosity reveals existence of a range of nanoparticle concentration and temperature in which the viscosity of nanofluid is lower than that of propylene glycol, possibly due to interactions between nanoparticles and propylene glycol. A temperature-independent, thermal conductivity enhancement of 38% was obtained for nanoparticle concentration of 1.5 vol% over a temperature range of 10-60 degrees C. We believe that particle clustering contributes to the thermal conductivity enhancement in CuO-propylene glycol nanofluids.
进行了关于氧化铜-丙二醇纳米流体的制备与表征的实验。纳米颗粒浓度和温度对纳米流体粘度的影响表明，存在一定范围的纳米颗粒浓度和温度，在此范围内纳米流体的粘度低于丙二醇的粘度，这可能是由于纳米颗粒与丙二醇之间的相互作用所致。在10 - 60摄氏度的温度范围内，对于1.5体积%的纳米颗粒浓度，获得了与温度无关的38%的热导率增强。我们认为颗粒团聚有助于氧化铜-丙二醇纳米流体的热导率增强。
