The purpose of current article is to simulate melting of NEPCM inside a cylinder with V shaped fins. Two dimensional transient formulations were modeled via finite volume method. Copper oxide nanoparticles were dispersed into paraffin. Second law treatments during melting are reported. Outputs illustrate that thermal entropy generation detracts with augment of temperature. Temperature rises as time progress due to stronger buoyancy forces.
