摘要

为研究不同金属泡沫铜填充率下金属泡沫铜对石蜡融化过程的传热规律

设计并搭建了一套可视化蓄能实验装置

并建立了对应的数学传热模型

分析了不同填充率下复合相变材料在融化过程中温度分布、固液相界面、速度矢量、液相分数和平均Nu的变化

得到了不同填充率下金属泡沫铜对石蜡相变过程的强化传热机理

并进行了实验验证。结果表明:当金属泡沫铜的填充率从0增大至1.28%时

复合相变蓄热材料的融化时间从901 s缩短至830 s

较纯石蜡减少了7.88%

而当泡沫铜填充率为1.28%时

石蜡内部温度为12.6 K

梯度最小; 平均Nu从24.89下降到3.27

下降了86.9%。由模拟结果可得

填充率为0.43%、1.28%的复合相变材料液化速率较纯石蜡分别提高了1.61%、7.11%

这说明金属泡沫铜的填充率越大

强化传热效果越好。

Abstract

In order to explore the influence of copper foam filling on internal heat transfer during paraffin melting

a set of visual energy storage experimental device is designed and built

and its mathematical heat transfer model is established accordingly. The changes in temperature distribution

solid-liquid interface

velocity vector

liquid fraction and mean Nusselt number of composite phase change materials with different filling rates during melting are analyzed

and the mechanism of enhanced heat transfer of paraffin wax by copper foam filling rate is concluded. The results show that when the copper foam filling rate increases from 0% to 1.28%

the melting time of composite PCM decreases from 901 s to 830 s

showing a reduction of 7.88% than that of pure paraffin wax. At the copper foam filling rate of 1.28%

paraffin wax gains the smallest temperature gradient of 9.1 K. According to the simulation results

the liquefaction rates of the composite phase change materials with filling rates of 0.43% and 1.28% are 1.61% and 7.11% higher than those of pure paraffin

respectively. This indicates that higher copper foam filling rate leads to better enhanced heat transfer effect.
