Melting thermal performance of a vertical cylindrical thermal energy storage unit is numerically investigated in presence of a phase change material (PCM) including nanoparticles (nano-PCM) and also horizontal radial copper fins .The results indicate that an increase in the number of fins will improve the heat transfer with subsequent reduction (up to 25.7%) in the melting time. But, use of nano-PCM without fin can only improve the melting time up to 5.5% for the case including 5% of nanoparticles. The best result corresponds to the case with simultaneous use of nano-PCM (5% of Al2O3) and fins (three fins) that could improve the melting time up to 28.3%.
