It is of interest to compare identical simulations to identify operational differences between the two different concrete TES designs. The mass flow rate profile used for each test is shown in Figure 5. There is a brief standby mode between charging and discharging sessions. A dual-pipe configuration could charge and discharge at the same time, but a single-pipe system would be restricted to either charging or discharging. The mass flow rate is thus set up for the more restrictive, single-pipe, case. Figure 5. Mass flow rate during test case. Negative flow rate indicates discharging flow. 2.2.1 Single-Pipe Model Results Figure 6 shows system temperatures from the last day of a 10-day cyclic simulation of the single-pipe concrete system. The solid lines are axial temperatures from hot end to cold end, while the two dotted lines are the fluid temperatures in those ports. It can then be observed that during discharging (before the first vertical discontinuity), the exit hot side fluid temperature remains below the concrete surface temperature. During charging, the concrete temperature increases and rises toward the inlet fluid temperature. The surface temperature changes quickly when the operating mode changes. Figure 6. Dashed lines show the hot-end (pink) and cold-end (black) fluid temperatures. The solid lines are concrete surface temperature at the hot-end (blue), cold-end (green), and axial center (red) temperatures. All temperatures are in °C. 7PDF Image | Thermal Energy Storage Model Development
