The Thermal Response of a Packed Bed Thermal Energy Storage System upon Saturated Steam Injection Using Distributed Temperature Sensing

Zayed Ahmed et al.

Summary: This study investigates the evolution of temperature gradients during saturated steam injection in a packed bed. The results show that the temperature gradients become steeper with increasing steam injection flow rates. Additionally, a distinct conduction zone is observed at low flow rates. These findings are important for understanding the effectiveness and efficiency of thermal energy storage systems.
