Resum
A numerical simulation model of thermal energy storage systems with encapsulated PCM is presented. In previous papers (Galione et al., 2011), the performance of cylindrical containers filled with PCM spheres and liquid fluids occupying the rest of the space was studied. Different charging and discharging processes were not only numerically analyzed, but also experimentally tested.

A numerical simulation model of thermal energy storage systems with encapsulated PCM is presented. In previous papers (Galione et al., 2011), the performance of cylindrical containers filled with PCM spheres and liquid fluids occupying the rest of the space was studied. Different charging and discharging processes were not only numerically analyzed, but also experimentally tested. Based on these numerical simulation tools for predicting the thermal and fluid dynamic behavior of these systems, new PCM tanks built in different solid filled materials and encapsulated PCMs combined into multi-layer storage with molted salt as heat transfer fluid are here presented. A virtual prototype proposed is numerically analyzed, while performance behavior is presented under different devices (charging and discharging conditions, PCMs temperatures, and multilayer configurations). The efficiency of these new configurations is also compared against conventional thermocline, showing the better option depending on cases and/or plants proposed.
