Cyclic performance of cascaded latent heat thermocline energy storage systems for high-temperature applications

Impact of buoyant jet entrainment on the thermocline behavior in a single-medium thermal energy storage tank

“…Single-tank thermocline TES systems can be subdivided into single-medium thermocline (SMT) and dual-medium thermocline (DMT). In SMT system only the HTF itself serves as the heat storage medium whereas in DMT, in addition to the HTF, solid fillers (sensible, latent, or a combination of both) are also used to increase the energy storage capacity and the cost competitiveness [5,6]. Among them, SMT systems have shown the advantages such as the simple implementation, relatively easy operation and high efficiency [7,8], with renewed attention being given to its potential applications in various fields.…”

Experimental Study of Simultaneous Charging and Discharging Process in Thermocline Phase Change Heat Storage System Based on Solar Energy

“…Elfeky [23,24] investigated six different multi-layer TES tank configurations, including the influence of different charge/discharge switching temperatures on the dynamic performance of the thermocline tank, and compared the charge/discharge time, temperature distribution of the molten salt, the recovered energy, the total efficiency, the capacity rate, and the utilization rate of all six of the configurations for three different stages. ELSihy et al proposed a transient two-dimensional model and analyzed the influences of the diameter of the spherical PCM capsules and the HTF inlet flow rate on the discharging performance and the thermocline thickness of different molten salt packed bed TES systems [25], investigated the influences of volume fraction of PCM on dynamic performance for multi-layer TES tanks, and then found the highest performance configuration [26].…”
