Résumé
Researchers have recently utilized and examined rock beds as one of the viable choices for sensible heat storage methods. This system's primary benefits are its inexpensive cost and the availability of rock used in the bed to store thermal energy. During the charging process, the heat transfer fluid passes through the pores of the rock bed, storing heat in the bed's solid matrix. The bed's porous structure allows fluids, whether compressible or incompressible, to pass through it, retaining heat in the solid portion of the porous area. In the discharging process, the fluid, on the other hand, takes the stored heat on demand. Researchers have been working diligently to study fluid flow and heat transfer in the porous structure of rock beds, as these areas are complex due to their heterogeneous nature in real-world applications. Although heat transport in rock beds has been extensively studied experimentally and modeled numerically, there is no support for Local Thermal Non-Equilibrium (LTNE)-based thermal models, particularly for horizontal cylindrical magnetite rock beds. There is a knowledge gap regarding the dynamics of heat retention in rock beds with air flow and under low-temperature conditions, as most research focuses on packed bed systems with water-based fluids and high-temperature conditions. This work bridges this gap by experimentally examining the heat storage and discharge dynamics in a cylindrical, horizontally aligned magnetite rock bed. The acceptable accuracy of the developed model is demonstrated by the numerical results derived from the proposed LTNE model. The experimental and numerical outcomes exhibit a maximum error of 6%.
