| Abstract: | Casing type high temperature thermal energy storage （ TES ） unit was designed and constructed .The TES unit contains Mg-Cu-Zn alloy as phase change material , air as heat transfer fluid （ HTF） .Fluent software was used to perform numerical simulation, and experiments were carried out to examine the effects of flow rate of HTF on the performance of the storage unit.The efficiency of heat discharging process was adopted as the index of thermal storage equipment heat exchange performs . The results show that the trends of numerical results and experimental data are in close agreement ; the maximum error between them is only 6%.The results laid a theoretical foundation for optimization design and engineering application of high temperature TES. |
