| Abstract Scope |
Latent heat thermal energy storage (LHTES) systems using materials like MgCl₂ are more efficient than sensible heat systems due to higher energy density and high melting point over 700o C. PCM is sometimes embedded in a high conductive material like graphite foam to improve the overall heat transfer. However, moisture infiltration can degrade the PCM by initiating hydrolysis reactions, leading to the corrosion of storage containers and altering the PCM hydrous state, and thus its properties.
This study aims to evaluate the impact of change in hydrous states of the PCM on the thermos-mechanical performance of the LHTES. A mesoscale model of graphite foam with different hydrous states of MgCl₂ is created and its effective properties are derived using homogenization. Using these properties, heat transfer and stress analysis are performed to analyze the thermal performance and stresses arising due to different thermal expansion coefficients of the system components. |
