Thermal conductivity properties of non-polar hydrogenated based-oil dispersed with multi-walled carbon nanotubes (MWCNT) are investigated. The dispersion of MWCNT are carried out via two-step methods that utilizes the combination of hydrodynamic cavitation and ultrasonication dispersion at weight concentration of 25 ppm, 50 ppm and 100 ppm respectively. MWCNT structure and chemical compound was analyzed using TEM imaging and FUR analysis. The thermal conductivity of MWCNT-hydrogenated oil shows 9.8% enhancement at 100 ppm concentration as compared to 7.2% and 4.5% enhancement at 50 ppm and 25 ppm respectively. Various conventional thermal conductivity models were compared with experimental data obtained, of which Nan et al. model yields the closest result approximations at 25 ppm while other models underpredicted the thermal conductivity of MWCNT-hydrogenated oil nanofluid.
