ANSYS software was used to simulate the circular air duct of the solid electric heat storage body,and the temperature distribution and outlet temperature of the circular air duct were ob-tained according to the simulation cloud map.On the basis of the circular air duct,the shape of the air duct is changed,and the variable diameter air duct is numerically simulated and calculated,and the variable diameter air duct is the air duct that appropriately increases the inlet diameter and re-duces the outlet diameter.The simulation results show that the outlet temperature,outlet velocity and total heat transfer efficiency of the air duct are partially improved compared with the original circular air duct,and the average temperature of the regenerator of the variable diameter air duct decreases by 80.63K,the heat release performance is increased by 18.24％,and the total air heat transfer rate is increased by 23.90％,so that the heat release performance of the heat regenerator is optimized.
