Abstract

The sensible energy storage system offers a reliable solution to store excess thermal energy for a wide range of thermal applications. The thermal performance of the storage system largely depends on the temperature distribution in the storage matrix during the charging/discharging process. The present study experimentally investigates the concrete-based tubular storage system with a centrally located passage under varying heat transfer fluid (HTF) inlet temperature from 45 to 85 °C at a mass flow rate of 0.018 kg s⁻¹. The temperature–time history along radial and axial directions is discussed to understand the thermal behaviour of different regions in the storage system.

具有中心通道的管状储能系统的热特性

明智的储能系统为广泛的热应用提供了可靠的解决方案来存储多余的热能。储能系统的热性能在很大程度上取决于充放电过程中储能矩阵内的温度分布。本研究在质量流量为0.018 kg s - 1、传热流体进口温度从45℃到85℃变化的条件下，对具有中心通道的混凝土管式储水系统进行了实验研究。讨论了沿径向和轴向的温度-时间历史，以了解存储系统中不同区域的热行为。
