Preparation and characterization of Cu2O-TiO2 nanofluid

Nanofluids are engineered suspension of Nanoparticles in a suitable base fluid. Nanofluids have a wide range of applications in thermal cooling, direct absorption solar collectors, enhanced fuel efficiency, medical applications, etc. Nanofluids have been extensively studied for their thermal conductivity and are presently being investigated for their novel electrical, magnetic and optical properties. A wide range of metallic (Ag,Cu,Ti) and ceramic(TiO2, Cu2O, Al2O3) nanofluids with water and ethylene glycol have been extensively prepared and characterized for their thermal applications. The present work deals with preparation of Cu2O-TiO2 Nanofluid by the two step method and nanoparticles of Cu2O-TiO2 nanofluid are characterised by SEM,EDAX. The stability of the nanofluid is investigated by sedimentation method.
