The knowledge of the thermal properties such as melting point, latent heat of melting, specific heat, thermal diffusivity and thermal conductivity is crucial for the development of the phase change materials (PCMs) for LHES applications. Due to their good properties, aluminium based eutectic alloys have become the most widely studied metal-based PCMs. In the present study, latent heat of melting for Al-12.6% Si, Al-33.3% Cu, and Al-27.8% Cu-5.2% Si (mass %) eutectic alloys were calculated using the CALPHAD (CALculation of PHase Diagram) method and the optimized thermodynamic parameters from the literature. The results of calculations were compared with the experimental results from the literature and good mutual agreement was noticed. The obtained results indicate that the applied calculation approach can be successfully used to predict the latent heat of eutectic alloys.enaluminium alloysphase change materialeutecticlatent heatconferenceObject
