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 %.
