Abstract This paper presents the study of the influence of SiO2 nanoparticles, temperature and nanoparticles mass loads on the thermal conductivity of SiO2/liquid paraffin nanofluid in existence of oleic acid. Different temperatures and nano sized particles mass fractions ranging from 25 to 70 °C and 0.005% to 5%, respectively, were considered within the experimentations. The results clearly exhibited that the thermal conductivity of the nanofluid altered significantly with the temperature enhancement and by increasing in the mass fraction of the SiO2 nano sized particles in the basefluid, the thermal conductivity of the nanofluid raised. The empirical relation of the current research exhibits that for the relative thermal conductivity of SiO2-oleic acid/liquid paraffin nanofluid as parameters of nanoparticles mass fraction and temperature the extent of data deviation is lower than 10% and for that of the relative viscosity of the SiO2-oleic acid/liquid paraffin the data deviation is also

摘要 本文研究了SiO2 纳米粒子、温度和纳米粒子质量负载对SiO2/液体石蜡纳米流体在油酸存在下的热导率的影响。在实验中考虑了不同的温度和纳米颗粒质量分数范围分别为 25 至 70 °C 和 0.005% 至 5%。结果清楚地表明，纳米流体的热导率随着温度的升高而显着变化，并且随着基液中SiO2纳米尺寸颗粒质量分数的增加，纳米流体的热导率升高。
