Abstract: This study investigates the enhancement of heat transfer in Latent Heat Thermal Energy Storage (LHTES) systems by using internal fins within a rectangular enclosure. Using lauric acid as the Phase Change Material (PCM), the impact of different fin configurations on the melting process is examined. A numerical model, incorporating the enthalpy-porosity method, is developed to simulate the phase change within the PCM. The model considers the effects of fin geometry, including variations in fin length and positioning. Results indicate that strategically placed fins significantly improve heat transfer efficiency, reducing complete melting time by more than 50% compared to a configuration of uniform-length fins. This enhancement is attributed to increased convective heat transfer facilitated by the longer fin in the lower zone of the enclosure.
