In order to store the solar energy efficiently, high temperature phase change material (HTPCM) through dispersion of nanoparticles is reported. Based on the enthalpy-porosity approach, the numerical model is first validated by comparing the results of the reference. Then the melting processes of HTPCM with different mass fraction nanoparticles in an enclosure are conducted. Results show that nanoparticles can greatly increase melting rate, compared with that of HTPCM, so nanoparticle-enhanced phase high temperature change material (NEHTPCM) has a promising application for solar energy storage.
