摘要:
采用COMSOL Multiphysics计算流体动力学软件建立相变蓄热水箱的数值模型,通过实验验证数值计算模型的准确性,并对相变蓄热水箱结构进行优化.分析不同环形金属隔板分层数和隔板厚度对相变蓄热水箱蓄放、热过程的影响.结果表明:在相变层内部设置的环形金属隔板可改善相变蓄热水箱的运行特性;蓄热过程中,环形金属隔板分层数和隔板厚度的增加有利于固态相变材料熔化,潜热利用率得到提升;放热过程中,增设环形金属隔板能使相变材料达到更低的固相比;厚度为5 mm的环形金属隔板对促进相变材料液化、维持水温的作用强于厚度为2,10 mm的环形金属隔板.
Abstract:
The COMSOL Multiphysics computational fluid dynamics software was used to establish the numerical model of the phase-change heat storage tank. The accuracy of the numerical calculation model was verified through experiments, and the structure of the phase-change heat storage tank was optimized. The influence of different annular metal partition layer numbers and partition thickness on the heat storage and release process of heat storage tank were analyzed. The results show that the operation characteristics of the phase-change heat storage tank can be improved by installing annular metal partition in the phase-change layer. In the process of heat storage, the increase of the layer numbers and thickness of annular metal partition is conducive to the melting of solid phase-change materials, and the utilization rate of latent heat is improved. In the heat release process, the addition of annular metal partition can lower the solid ratio of phase-change material. The annular metal partition with a thickness of 5 mm plays a stronger role in promoting the liquefaction of phase-change materials and maintaining the water temperature than the annular metal partition with a thickness of 2, 10 mm.
