Investigating cold energy retention in advanced storage systems with complex geometries

Current study searches the cold storage unit incorporating an elliptical and sinusoidal structure, aimed at optimizing the solidification process through the integration of porous media. The combination of complex geometries, permeable materials, and hybrid nanoparticles significantly enhances freezing efficiency. A detailed mathematical model is developed, incorporating both conduction and radiation heat transfer mechanisms, and numerical simulations are conducted using the Finite Element Method. The model is thoroughly validated against established studies, demonstrating strong consistency with previous findings. The results reveal that hybrid nanoparticles reduce the freezing time by 7.24% and the adding of radiation effects further accelerates solidification by 12.66%. Additionally, the presence of porous structures improves cold energy retention by an impressive 91.2%, underscoring their vital contribution to thermal storage enhancement. This study offers valuable insights into advancing cold storage technologies, promoting greater energy efficiency and improved thermal management.
