Experimental investigation on thermo-physical properties of metal oxide composite nanolubricants

The thermal conductivity and dynamic viscosity of three different combinations of metal oxide composite nanolubricant had been investigated at different nanoparticle volume concentrations (0.02 to 0.1%) and different temperatures (303–353 K). The prepared Al2O3–SiO2, Al2O3–TiO2 and TiO2–SiO2 composi...
