| 摘 要： | 为了研究动力型分离式热管蓄能装置中相变材料(PCM)的蓄能和释能过程中的传热情况,进行了热管蓄能装置蓄能和释能过程的数值模拟。建立了动力型热管蓄能装置蓄能及释能过程的物理模型,采用Solidification/Melting模型对热管内部的蓄能和释能过程进行了数值模拟分析,得到了动力型分离式热管稳定运行时的温度分布和液相率分布,并探讨了蓄能和释能过程所用的时间以及PCM在各个时间节点的温度值,计算结果与实验结果的对比表明两者吻合性较好。

| Abstract: | The energy storage and release process in the power type separated heat pipeenergy storage device were numerically simulated in order to analyze the heat transfer of PCM in the energy storage and release process of the heat pipe energy storage device. The physical model of energy storage and release process of heat pipe energy storage device was established. By using Solidification/Melting model, the energy storage and release process in the heat pipe were simulated to obtain the temperature distribution and the liquid phase ratio distribution of power type separated heat pipe under steady state. The time of energy storage and release process of energy storage material and the temperature value of PCM at each time node were discussed. Moreover, the comparison result indicates that there is a good agreement between the numerical simulation results and the experimental results. |
