A study on the thermo physical and tribological characteristics of graphene sunflower oil nanofluid

Abstract

In the past decades considerable effort have been given for the development of energy efficient and eco-friendly convective heat transfer and lubricating agents because of growing energy demands, precision manufacturing, miniaturization and sustainability issues. Nanofluids and nanolubricants have been discovered as unique working fluids prepared by dispersing nanoparticles into a fluid medium. The nanofluids are proved as a superior heat transfer and lubricating agent in this regard due to the enhanced heat transfer capability and lubricating distinctiveness than the traditional working fluids. In this study, different concentrations of Graphene-sunflower oil nanofluids were prepared and their dispersion stability, thermo-physical and tribological characteristics were experimentally investigated and compared with the correlations of similar research found in literature. newline
