This paper presents results of an experimental study of the den- sity, saturated vapor pressure, surface tension and viscosity of Al2O3 nanopar- ticle solutions in isopropyl alcohol. Studies of the thermophysical properties of nano uids were performed at various temperatures and concentrations of Al2O3 nanoparticles. The paper gives considerable attention to a turbidimet- ric analysis of the stability of nano uid samples. Samples of nano uids re- mained stable over the range of studied parameters, ensuring the reliability of the thermophysical property data for the Al2O3 nanoparticle solutions in isopropyl alcohol obtained in this study. The studies show that the addition of Al2O3 nanoparticles leads to an in- crease in density, saturated vapor pressure, and viscosity, as well as a decrease in the surface tension of isopropyl alcohol. The information reported in this paper on various thermophysical properties for the isopropyl alcohol/Al2O3 nanoparticles model system is useful for the development of thermodynami- cally consistent methods for predicting properties of nano uids and modeling heat exchange processes.
