The physical mathematical model of the gas loss through the packed bed of irregular heat regenerator was established. The main influencing factors were analyzed and the theoretical analysis formula of the resistance calculation was established. By setting up the experimental equipment of the bed resistance characteristics, the air flow and temperature were adjusted, Size regenerator to obtain the relevant experimental data to determine the relevant constants in the bed resistance coefficient f and the correction term of the influence of the boundary layer so as to obtain the formula for calculating the resistance loss of the gas flowing through the irregular bed of the regenerator, It provides a theoretical basis for the industrial design of high-temperature solid-state heat accumulators in the CSP system.
