本文探讨了蓄热作为一种具有成本优势的储能技术的潜力。采用数值模拟的方法，研究了采用AlSi12合金作为相变材料的TES在凝固过程中加入多孔材料对改善TES换热效果的影响。研究还考察了添加多孔介质材料和提高风速对高温相变储能系统放电温度、放电功率和放电时间的影响。研究发现，在HTF管中添加不同的多孔材料(泡沫铜、泡沫镍和碳化硅)，相变材料的温差(增加)、固化时间(减少了85%以上)、空气出口温度和放热功率没有显著差异。这些发现为高温相变储能装置的设计提供了重要信息，并可指导该领域未来的发展。
This paper explores the potential of thermal storage as an energy storage technology with cost advantages. The study uses numerical simulations to investigate the impact of adding porous material to the HTF side during solidification to improve the heat transfer effect of TES using AlSi12 alloy as the phase-change material. The research also examines the effects of adding porous dielectric materials and increasing air velocity on the discharge temperature, discharge power, and discharge time of high-temperature phase-change energy storage systems. The study found that the temperature difference of the PCM (increased), solidification time (reduced more than 85%), the outlet temperature of the air, and heat discharge power of the LHS did not vary significantly across different porous materials (copper foam, nickel foam, and silicon carbide foam) added to the HTF tube. These findings offer important information for the design of high-temperature phase-change energy storage devices and can guide future developments in this field.
