Dynamic performances of solar heat storage system using packed bed
The objective of this paper is to study the dynamic performance of solar heat storage using packed bed with spherical capsules during discharging process. According to the energy balance, a dynamic discharging processes model of packed bed with spherical capsules is simulated. Paraffin is taken as phase change material (PCM) and water is used as heat transfer fluid (HTF). The temperatures of PCM and HTF, solid fraction and heat released rate are simulated. The effects of inlet temperature of HTF, flow rate of HTF and porosity of packed bed on the time for discharging and heat released rate are also discussed.
