The performance of latent heat thermal energy storage (LHTES) systems can be significantly enhanced by improving the properties phase change materials (PCMs). Today, these serve as a sustainable resource and find applications in various sectors, including conservation buildings, household hot water systems, air conditioning units, peak load reduction, waste recovery, biomedical applications. This paper investigates effects fins metal foam on melting solidification rates PCM within spherical unit (LHTESU). To assess impact fin geometry efficiency, three types were tested: with constant length, variable curved-shaped fins. Additionally, different porosity levels considered. A finless reservoir filled was used baseline benchmark to evaluate enhancements provided configurations. results indicated that utilizing seven fixed-length thickness 1 mm represents most effective configuration for increasing among volume fraction cases, leading reductions times 58.76% 72.66%, respectively. Furthermore, incorporating improved rate PCM, achieving time 89.11% 94.96% when 85% used. These highlight potential advanced designs porous media enhancing offering promising insights future technologies.
