摘要

为解决相变材料胶囊(PCMC)结构优化方案因量产成本高而难以实现工程规模化应用的问题，本研究基于Fluent软件建立三维非稳态焓法模型，对易于工业化生产且内切球球心与几何中心重合的球体、圆柱体、正方体、圆锥、三棱柱以及正四面体PCMC的蓄冷过程进行分析。结合液相率、温度场、蓄冷量、蓄冷速率以及傅里叶-斯特凡数，对比不同形状对PCMC蓄冷性能的影响，并探究蓄冷过程的内在影响因素。研究结果表明，形状对PCMC蓄冷性能的影响显著，通过内切球半径影响传热过程，且当内切球半径减小时，PCMC的蓄冷性能提升。正四面体相变材料胶囊(RTPCMC)性能最优且内切球半径最小，球形相变材料胶囊(SPCMC)性能最差且内切球半径最大。与SPCMC相比，RTPCMC的凝固时间、蓄冷完成时间和内切球半径分别减小34.29%、29.33%和36.2%，平均傅里叶-斯特凡数和平均蓄冷速率分别提升261.81%和29.44%。此外，PCMC的填充率随内切球半径的减小呈缓慢线性下降趋势，而比表面积随半径减小则表现为快速线性增大趋势。在体积、壁厚相同且内切球球心与几何中心重合的条件下，减小内切球半径是提高PCMC蓄冷效率的有效手段。

Abstract

To address the limited engineering applicability of phase change material capsule (PCMC) structural optimization schemes caused by high large-scale production costs

a three-dimensional unsteady enthalpy model was established in this study using Fluent. The model was applied to analyze the cold storage process of PCMCs with shapes suitable for industrial production and with the inscribed sphere center coinciding with the geometric center

including sphere

cylinder

cube

cone

triangular prism

and regular tetrahedron. Based on the liquid fraction

temperature field

cold storage capacity

cold storage rate

and Fourier–Stefan number

the effects of capsule shape on cold storage performance were systematically compared

and the intrinsic influencing factors governing the cold storage process were investigated. The results indicate that capsule shape has a significant effect on the cold storage performance of PCMCs by influencing the heat transfer process through the inscribed sphere radius. A decrease in the inscribed sphere radius leads to improved cold storage performance. Among the investigated geometries

the regular tetrahedral phase change material capsule (RTPCMC) exhibits the best performance and the smallest inscribed sphere radius

whereas the spherical phase change material capsule (SPCMC) shows the poorest performance and the largest inscribed sphere radius. Compared with SPCMC

the solidification time

cold storage completion time

and inscribed sphere radius of RTPCMC decrease by 34.29%

29.33%

and 36.2%

respectively

while the average Fourier-Stefan number and average cold storage rate increase by 261.81% and 29.44%

respectively. In addition

the filling rate of PCMCs shows a slow linear decrease with decreasing inscribed sphere radius

whereas the specific surface area exhibits a rapid linear increase. Under conditions of identical volume

wall thickness

and coincident inscribed sphere and geometric centers

reducing the inscribed sphere radius is an effective approach for enhancing the cold storage efficiency of PCMCs.
