Optimization Design and Analysis of Pore Ratio Structure of Solid Electric Heat Storage Body Applied to Intelligent Park Heating

摘要

Smart Park adopts solid electric heat storage device for heating. Energy storage can store electric energy into heat energy and play an advantage in peak load rule. The heat transfer performance of regenerator in solid electric energy storage system is studied. According to the characteristics of the built-in resistance regenerator and the heat transfer theory of fluid structure coupling, the three-dimensional numerical simulation of the flow field and temperature field coupling of the regenerator is carried out. The simulation results are compared with the experimental data to verify the correctness of the simulation results. At the same time, the best design and analysis of the regenerator with different void ratio are carried out. The results show the structure with 20% porosity is ideal considering the heat storage and release properties.
