Abstract: Thermal energy storage (TES) systems are essential for improving energy efficiency and facilitating the use of renewable energy sources. This research examines the performance of a TES system that employs cylindrical encapsulated phase change materials (PCMs) to enhance thermal regulation and optimize energy storage capabilities. The encapsulation of PCM in cylindrical containers ensures structural stability, reduces leakage, and enhances thermal conductivity through optimized heat transfer surfaces. A comprehensive experimental and numerical analysis is conducted to evaluate the thermal performance, charging/discharging characteristics, and energy storage capacity of the system. Key parameters such as heat transfer rates, melting and solidification times, and thermal stratification are examined. The effects of PCM properties, encapsulation dimensions, and operating conditions on system efficiency are analyzed. The findings demonstrate that cylindrical encapsulated PCM enhances thermal energy storage efficiency by offering greater energy density, improved thermal stability, and a more uniform temperature distribution. The findings demonstrate that this approach can be effectively applied to solar energy systems, HVAC systems, and industrial waste heat recovery processes. This research contributes to the development of advanced TES systems by addressing challenges related to heat transfer enhancement and energy storage efficiency, promoting sustainable energy solutions.
