This paper presents study of effective thermal conductivity of ZnO nanofluid.. The nanofluid was prepared by dispersing Zno nanoparticles in ethylene glycol. Ethylene glycol based nanofluid containing ZnO nanoparticle at various temperatures was examined for the investigation. The thermal conductivity of nanofluids is experimentally measured with conventional method and it is found that the thermal conductivity of nanofluids increase with the nanoparticle volume concentration and temperature.
