摘要: 应用数值模拟的方法对旋转式三角形管相变蓄热器蓄热性能进行研究，并进行了相变区域的场协同分析。研究结果表明，和非旋转模型相比，旋转模型可显著提升相变蓄热器蓄热效果，缩短蓄热时间，蓄热效率总体可提高80%左右。但转速并非愈高愈好，从节能和场协同性角度综合考虑，不宜过高提升转速，本文计算参数下3 rad/s为最佳转速。
Abstract: The heat storage performance of rotating phase change heat accumulator with triangular tube is studied by numerical simulation method, and the field synergy analysis of phase change region is carried out. The results show that compared with the non-rotating model, the rotating model can significantly improve the heat storage efficiency, shorten the heat storage time, and increase the heat storage efficiency by about 80%. But not the higher the speed is, the better it is. From the perspective of energy saving and field synergy, it is not suitable to raise the speed too high. The optimum speed is 3 rad/s according the calculation in this paper.
