<br/><br/> The aim of this research is to study the influence of adding Multi- Walled Carbon Nanotube (MWCNTs) and graphene nano sheet (GNS) on the rheological behavior, tribological properties and thermal conductivity.  The rheological and tribological behaviors of nanofluids having CNTs and GNS additives indicated that the shear stress, apparent viscosity , thermal conductivity,  friction coefficient and WSD improved at 3% of CNTs and GNS
