This paper presents the pool boiling process of argon atoms on the copper surface by employing molecular dynamics simulation. Through the application of molecular dynamics simulation, this study explores three cases: the plain surface, and adding platinum and aluminum nanoparticles to the argon fluid. The main objective is to offer a comprehensive comparative analysis to highlight the significance and innovation of this research. The investigation aims to assess the effectiveness of two methods for improving heat transfer: the addition of nanoparticles to the base fluid and the creation of porous nanostructure. By subjecting these approaches to identical simulation conditions, an enthralling evaluation unfolds. The simulation framework is first validated, and then the results are presented and compared with the case of creating porous geometry. The results reveal that while the evaporation rate has a similar impact in both cases, creating porous geometry results in a 3.68% higher argon temperature compared to adding nanoparticles. On the other hand, adding nanoparticles enhances the maximum heat flux by approximately 15% more than creating porous geometry. This research compares two approaches to offer valuable investigations and insights into enhancing heat transfer efficiency due to the growing demand for strategies that promote heat transfer.
