In this paper, an experimental study of convective heat transfer and pressure drop of turbulent flow of TiO2-water nanofluid through a uniformly heated horizontal circular tube has been performed. The spherical TiO2 nanoparticles with a nominal diameter of 15nm are functionalized by a new chemical t...
