Investigation of Thermal Conductivity and Viscosity of Al2O3/PAG Nanolubricant for Application in Automotive Air Conditioning System

In this paper, thermal conductivity and viscosity of the Al2O3/polyalkylene glycol (PAG) 46 nanolubricants for 0.05 to 1.0% volume concentrations at temperatures of 303.15 to 353.15 K have been investigated. Al2O3 nanoparticles were dispersed in the PAG lubricant by a two step preparation. The measu...
