This compact structure along with limitation at the surface of the fins is simulated using Finite Element Method (FEM). Mixture of copper oxide and H2O is introduced as a working fluid. Moreover, the nanoparticle-enhanced phase change materials (NEPCM) shows a significant change in thermal behavior of nanofluid and pure PCM properties by considering the Brownian motion. The outcomes are depicted in the form of temperature, solid fraction and phase change front contours. The results are obtained to determine the variation of phase change by adding the nanoparticles in PCM for various time domains. Similarly, significant effects of nanoparticles volume fraction on the total energy and solid fraction are presented. Furthermore, it is found that the nanoparticles and radiation parameter with size of dp = 40 nm has the greatest heat transfer rate.
