The effects of different heat transfer fluid (HTF) parameters on charging and mechanical performance of the thermal energy storage (TES) tank using phase change material (PCM) capsules are studied by employing the fluid-solid coupling calculation. The results show that, with the inlet HTF flow velocity increased from 0.000 7 m/s to 0.000 9 m/s, the total heat storage quantity is basically unchanged, the average charging power increases from 5.33 MW to 6.79 MW, and the peak maximum mechanical stress (MMS) of the tank wall decreases. When the initial cold HTF temperature decreases from 610 K to 530 K, the total heat storage quantity increases, the average charging power increases from 5.29 MW to 6.81 MW, but the peak MMS of the tank wall also increases. With the initial hot HTF temperature increases from 730 K to 810 K, the total heat storage quantity increases obviously, the average charging power increases from 3.81 MW to 7.97 MW, but the peak MMS also increases to 159.6 MPa. Hence, to improve the charging performance of the TES tank, on the premise of ensuring the structural safety of steel wall of the TES tank, the inlet HTF flow velocity and initial hot HTF temperature should be increased properly, and the initial cold HTF temperature should be reduced properly.

基于流固耦合方法,探究了不同传热介质(HTF)参数对填充球形相变材料(PCM)胶囊的单罐储热(TES)系统蓄热性能和力学性能的影响。结果表明:随着HTF进口流速从0.000 7 m/s增大到0.000 9 m/s,TES罐的蓄热总量没有显著变化,但其平均蓄热功率从5.33 MW增大至6.79 MW,且钢壁的最大机械应力减小;随着初始冷HTF温度从610 K降至530 K,TES罐的蓄热总量增大,平均蓄热功率从5.29 MW增至6.81 MW,但钢壁最大机械应力也增加;当初始热HTF温度从730 K上升到810 K,TES罐的蓄热总量显著提高,且平均蓄热功率由3.81 MW增大到7.97 MW,但钢壁的最大机械应力也增至159.6 MPa。因此,为了优化PCM胶囊TES罐的蓄热性能,除了适当提高HTF进口流速外,应在保证TES罐钢壁结构安全的条件下,适当降低初始冷HTF温度或提高初始热HTF温度。

基于流固耦合方法,探究了不同传热介质(HTF)参数对填充球形相变材料(PCM)胶囊的单罐储热(TES)系统蓄热性能和力学性能的影响。结果表明:随着HTF进口流速从0.000 7 m/s增大到0.000 9 m/s,TES罐的蓄热总量没有显著变化,但其平均蓄热功率从5.33 MW增大至6.79 MW,且钢壁的最大机械应力减小;随着初始冷HTF温度从610 K降至530 K,TES罐的蓄热总量增大,平均蓄热功率从5.29 MW增至6.81 MW,但钢壁最大机械应力也增加;当初始热HTF温度从730 K上升到810 K,TES罐的蓄热总量显著提高,且平均蓄热功率由3.81 MW增大到7.97 MW,但钢壁的最大机械应力也增至159.6 MPa。因此,为了优化PCM胶囊TES罐的蓄热性能,除了适当提高HTF进口流速外,应在保证TES罐钢壁结构安全的条件下,适当降低初始冷HTF温度或提高初始热HTF温度。

The effects of different heat transfer fluid (HTF) parameters on charging and mechanical performance of the thermal energy storage (TES) tank using phase change material (PCM) capsules are studied by employing the fluid-solid coupling calculation. The results show that, with the inlet HTF flow velocity increased from 0.000 7 m/s to 0.000 9 m/s, the total heat storage quantity is basically unchanged, the average charging power increases from 5.33 MW to 6.79 MW, and the peak maximum mechanical stress (MMS) of the tank wall decreases. When the initial cold HTF temperature decreases from 610 K to 530 K, the total heat storage quantity increases, the average charging power increases from 5.29 MW to 6.81 MW, but the peak MMS of the tank wall also increases. With the initial hot HTF temperature increases from 730 K to 810 K, the total heat storage quantity increases obviously, the average charging power increases from 3.81 MW to 7.97 MW, but the peak MMS also increases to 159.6 MPa. Hence, to improve the charging performance of the TES tank, on the premise of ensuring the structural safety of steel wall of the TES tank, the inlet HTF flow velocity and initial hot HTF temperature should be increased properly, and the initial cold HTF temperature should be reduced properly.
