This project aims to enhance heat transfer in latent heat thermal energy storage (LHTES) systems with Salt Hydrate 36 as the phase change material (PCM). Latent heat storage has a high energy density and is best suited for applications where stable thermal management is needed. Nevertheless, the intrinsic low thermal conductivity of most PCMs, such as Salt Hydrate 36, restricts heat transfer rates, which affects the efficiency and response time of such systems. The main objective of this research is to examine ways of increasing the thermal conductivity of Salt Hydrate 36. Major strategies considered involve the incorporation of high-conductivity materials, including metal fins, graphite, or nanoparticles, to enhance the thermal performance during melting and solidification. Experimental configurations and simulations are performed to evaluate heat transfer properties, energy storage efficiency, and cycle stability under various configurations. Results show that its optimized thermal conductivity enhancement dramatically lessens charging and discharging periods without diminishing its latent heat capability. Such advancement in thermal performance is highly desired for applications towards solar energy storage, building interior temperature control, and industrial waste heat recovery.
