AB - Enhancement of thermal and heat transfer capabilities of phase change  materials with addition of nanoparticles is reported. The mixed nanofluid of  phase change material and nanoparticles presents a high thermal conductivity  and low heat capacity and latent heat, in comparison with the base fluid. In  order to present the thermophysical effects of nanoparticles, a  solidification of nanofluid in a rectangular enclosure with natural  convection induced by different wall temperatures is considered. The results  show that the balance between the solidification acceleration by  nanoparticles and slowing-down by phase change material gives rise to control  the medium temperature. It indicates that this kind of mixture has great  potential in various applications which requires temperature regulation.  Also, the Brownian motion of nanoparticles enhances the convective heat  transfer much more than the conductive transfer.
