Inclusion of nanoparticles in PCM for heat release unit

Abstract Main motivation of present work is to scrutinize the solidification of CuO-water within unit with innovative fins. This compact structure along with limitation at the surface of the fins is simulated through FEM. Mixture of copper oxide and H2O is introduced as a working fluid. Moreover, the nanoparticle-enhanced phase change materials (NEPCM) shows the significant change in thermal behavior of nanofluid and pure PCM properties by considering the Brownian motion. Outputs are depicted in the form of temperature, solid fraction and phase change front contours. 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 total energy and solid fraction are presented. Furthermore, nanoparticles and radiation parameter with size of dp = 40 nm has the greatest heat transfer rate.
