Thermochemical energy storage operates in open or closed systems, where thermal transport is always involved. The heat transfer strongly affects the storage performance of the system. In order to design an appropriate and successful storage system, it is very essential to know the thermal properties of the used material. In low-temperature applications of particulate multiphase systems such as packed beds where gas-solid interacts, the conduction plays a more prominent part for heat transfer compared to convection and radiation. Thus, investigation and evaluation of the thermal conductivity of the used material are necessary. This paper presents a numerical method for the thermal heat exchange by conduction and radiation through a packed bed. The produced results for heat transfer are compared with the measurements of the effective thermal conductivity experiments. This method enables us to explore the effective thermal conductivity of the bed and effects of particle packing density on the heat transport processes in packed beds as it allows performing real-time simulations at large scale involving different initial and physical conditions.
