Abstract
Recent studies in heat transfer evident that the nanofluid shows better heat transfer results as compared to base fluid. This influences the research community for the dispersion of nanoparticles in lubricants to enhance its thermophysical and tribological properties and these suspensions are termed as Nanolubricants. This review focuses on the effect of nanoparticle additives on thermophysical and tribological properties of base lubricant. Initial section briefly summarizes the variation in thermophysical properties namely viscosity, thermal conductivity, density and specific heat of nanolubricants. In later section, the coefficient of friction and anti-wear properties of nanolubricants are summarized. This review along with the replenishment of current knowledge, also discusses the fundamental mechanisms that evolve with the dispersion of nanoparticles.
