Description
Summary:This paper presents measurements of specific heat and density of aluminum oxide (Al2O3) nanoparticles suspended in 60:40 (by mass) ethylene glycol and water mixture (EG/W). These property values are necessary to determine the fluid dynamic and heat transfer characteristics of nanofluids. These properties have been measured over a range of temperatures for nanoparticle volumetric concentrations of 0 to 10%. From the experimental results, empirical correlations have been developed as a function of temperature and particle volume concentration. These correlations will be valuable in studying the heat transfer performance and the pumping power requirement of Al2O3 nanofluid in various applications such as industrial heat exchangers, building heating and automotive cooling.
