The heat transfer enhancement in the latent heat thermal energy storage
system through dispersion of nanoparticle is reported. The resulting
nanoparticle-enhanced phase change materials (NEPCM) exhibit enhanced thermal
conductivity in comparison to the base material. The effects of nanoparticle
volume fraction and some other parameters such as natural convection are
studied in terms of solid fraction and the shape of the solid-liquid phase
front. It has been found that higher nanoparticle volume fraction result in a
larger solid fraction. The present results illustrate that the suspended
nanoparticles substantially increase the heat transfer rate and also the
nanofluid heat transfer rate increases with an increase in the nanoparticles
volume fraction. The increase of the heat release rate of the NEPCM shows its
great potential for diverse thermal energy storage application.
