摘      要：Using our reported experimental data of effective thermal conductivity,specific heat capacity and viscosity for CuO nanoparticle suspensions,the corresponding thermal diffusivity and Prandtl number are *** the hard sphere model and consid-ering effects of particle clustering and surface adsorption,the increase of viscosity for nanoparticle suspension observed is *** is shown that the effective thermal conductivity will be strongly affected by the formation and correlated spatial distribution of nanoparticle clusters when compared to viscosity in hosting liquid.
