摘要

本文研究了主动旋转作用下相变储能单元的凝固性能。以具有4片金属翅片的三管相变储能结构为研究对象,建立了全面的数值模型并进行了验证。研究了不同旋转速度和旋转中心距离下装置的凝固时间、放热速率、能量释放和无因次温度响应。结果表明,当旋转中心距为200 mm和300 mm,转速为0.1 rpm时,案例1的凝固时间分别缩短了54.96%和58.59%,平均放热率分别增加了121.17%和140.59%。然后以凝固时间和平均放热率为优化目标,采用田口法进行设计分析。转速的影响大于中心距的影响。交互作用分析表明,两个研究变量之间几乎不存在效应关系。与情况1相比,优化后的组织凝固时间明显缩短了73.92%。相比之下,平均放热率和平均温度响应分别提高了281.92%和278.13%。然而,在放热过程结束时的显热释放减少了1.32%。

Synergistic study of center distance and rotation speed under active rotation conditions on heat release process of phase change material
In this paper, the solidification performance of a phase change energy storage unit under the action of active rotation is studied. A comprehensive numerical model is established and verified by taking the triplex-tube phase change energy storage structure with 4 alternating metal fins as the research object. The solidification time, heat release rate, energy release, and dimensionless temperature response of the device under different rotation speeds and distances of rotation centers are studied. The comparison results show that the solidification time of Case 1 decreases by 54.96 % and 58.59 %, respectively, and the average heat release rate increases by 121.17 % and 140.59 %, respectively, when the rotation center distance is 200 mm and 300 mm at a constant rotation speed of 0.1 rpm. Then, taking solidification time and average heat release rate as optimization objectives, the Taguchi method is used for design analysis. The effect of rotation speed is higher than that of center distance. The interaction analysis shows that there is almost no effect relationship between the two study variables. Compared with Case 1, the solidification time of the optimal structure is significantly shortened by 73.92 %. In comparison, the average heat release rate and average temperature response increased by 281.92 % and 278.13 %, respectively. However, the sensible heat release at the end of the heat release process is reduced by 1.32 %.
