The efficiency of energy applications will gain importance throughout the next years. Development and optimization of future systems, needs to consider power supply, capacity, flexibility of system integrations and economic profitability. Thermal energy storage concepts based on macro-encapsulated phase-change material (PCM) promise to fulfill those requirements. One challenge is the change of physical properties of the PCM during its melting, which is here studied numerically and validated by experiments in this contribution. The numerical model, using the Volume of Fluid method and a detailed description of sensible and latent heat processes, discusses spherical encapsulated PCMs with different melting temperatures. The latent heat source term is computed and corrected through iteration. The numerical results, as verified for a single capsule through an experimental model, can be applied to the research of packed-bed PCMs.
