Synthesis and Characterization of TiO2 -CNTs Nanocomposite and Investigation of Viscosity and Thermal Conductivity of a New Nanofluid

Nanofluids are kinds of fluids engineered by dispersing nanoparticles in base fluids, a new challenge for thermal sciences provided by nanotechnology. Due to their excellent characteristics, nanofluids find wide applications in enhancing heat transfer. This paper presents synthesis and characterization of TiO 2 -CNTs nanocomposites by sonochemical method and investigation of some properties of TiO2 -CNTs nanocomposite suspended in 50:50 (by weight) propylene glycol and water mixture as a new nanofluid.
