Mitigation of the local overheating phenomenon in molten salt electric heaters through flow field optimization He X.; Wang Y.; Ren C.; Yu L.; Hu N.; Zheng C.; Gao X.
The local overheating phenomenon was found within MSEH. The relationship between the number of baffles and overheating was studied. A baffle opening design was introduced to eliminate local overheating phenomenon. A method for suitably adjusting the length of electric heating rods was proposed.
For the certain power, an increase in the cutoff temperature will effectively improve the energy storage density due to the higher average temperature difference between the heat source and PCM.
In summary, perforation of the baffle significantly alleviates the local overheating on the back of the baffle, except for the last baffle. Notably, the local overheating issue in the MSEH cannot be entirely resolved solely by perforating the baffle. Additional measures and strategies are necessary to address this issue at the tail end of the MSEH.
A coupled model was developed to study the molten salt electric heaters (MSEHs). The local overheating phenomenon was found within MSEH. The relationship between the number of baffles and overheating was studied. A baffle opening design was introduced to eliminate local overheating phenomenon.
The power (or specific power) of thermal storage refers to the speed at which heat can be transferred to and from a thermal storage device, essentially related to the thermal-transfer process and dependent on a variety of heat-transport-related factors, including heat flux condition, system design, and material properties.
When the straight pipe section of the heating rod is positioned slightly farther from the rear of the last baffle, the molten salt near the end of the electric heating rod, far from the back of the last baffle, may experience local overheating due to the limited jet strength at the opening.
