Abstract
In this study, the phase transition process of porous carbon matrix (PCM) containing paraffin as phase change materials (PCM) in copper oxide nanoparticles (NPs) is explored utilizing the molecular dynamics (MD) simulation procedure. PCMs can cumulate and disseminate huge energy due to their high melting heat. In this way, the changes in the charge time, discharge time, heat flux (HF), and phase transition time are studied. The effects of the nanoparticles percentage and the initial temperature (T) on the thermal manner of the atomic sample are studied. The nanoparticle's atomic percentage from 1 % to 5 % enhanced the HF from 1452 to 1726 W/m2 and decreased the phase transition time from 3.92 to 3.05 ns. So, the thermal manner of the atomic matrix progressed by increasing the percentage of nanoparticles, and phase transition occurred in a brief time. The initial T from 300 to 350 K enhanced the HF from 1452 to 1770 W/m2 and reduced the phase transition time from 3.92 to 3.73 ns.
