Abstract: 

Charging of PCM with incorporating copper oxide nanomaterial has been modeled in current article. Unsteady simulation for reporting thermal irreversibility was performed. Nanoparticles have been dispersed into paraffin to achieve greater efficiency and reach the match between demand and supply of energy. To increase the stored energy, volume fraction of copper oxide should be increased. Outputs revealed that narrow melt layer near the inner duct has been formed in initial time and it expanded as time progressed. Melting time and volume fraction of copper oxide has reverse relation and dispersing nanoparticles make entropy generation to decline.
