CFD Model Validation for Charging and Discharging of a PCM Encapsulated in Sphere

Abstract:

The application of phase change material (PCM) for thermal energy storage (TES) has become one of the viable solutions in energy saving achievable with renewable thermal systems. Packed bed of spheres has been used as TES to enlighten the encapsulated PCM availability in space within the TES system. In order to minimise the high manufacturing cost, the simulation on the TES model is proposed. In accordance to that, a model of TES containing a PCM sphere has been studied in this paper. A commercialised computational fluid dynamics (CFD) software is used to simulate the TES model and the result is then compared experimentally, thus validating the simulation model. The model has been validated for both charging and discharging processes. It is also found that with the use of the CFD model, one could determine the effective thermal conductivity of the PCM at different temperatures.
