Abstract Scope |
The focus of the presentation is on the development of a high efficiency latent heat based thermal energy storage (LHTES) system. As part of this work, we have impregnated high thermal conductivity, low-density graphite foams with a phase change material (PCM) magnesium chloride salt, thereby, offering a composite system with conductivities significantly greater than the salt alone, allowing rapid charge/discharge cycles. Three-dimensional heat transfer simulations were conducted for the storage system using commercial software COMSOL. The results show that the graphite foam can considerably enhance the heat transfer performance and round-trip efficiencies of the LHTES system. As part of this presentation, experimental results from lab-scale prototypes and the associated charging and discharging tests will be discussed and compared with the simulations. Role of potential material degradation(s) will be presented. |
