The efficient storage and utilization of thermal energy are crucial for advancing sustainable energy systems. Latent Heat Energy Storage Systems (LHESS) leverage the high energy density associated with phase transitions of Phase Change Materials (PCMs). providing an effective solution for thermal energy management. In this study, latent heat storage with cylindrical PCM capsules is analysed numerically. Detailed charging and discharging simulations during 5 hours are conducted to investigated temperature distribution, phase transition and stored thermal energy. Paraffin waxes were selected as a PCM due to their advantageous thermal characteristics, such as high latent heat of fusion, chemical stability, and non-corrosive nature. Results indicate that at the 5-hour mark, nearly all of the Phase Change Material (PCM) in LHESS has transitioned to the liquid phase when the charging simulation is conducted. Total accumulated energy was about 90000 [kJ] at defined points of LHESS. During discharging period, outlet temperature of LHESS is decreased to 315 [K] which makes it suitable for domestic application.
