Investigation of thermal conductivity of multi walled carbon nanotube dispersed in hydrogenated oil based drilling fluids

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 co...
