Abstract: Modeling and simulation based on computational fluid dynamics and heat transfer for the metal structured packed bed were carried out to predict the flow field and temperature field, and to evaluate its performance in heat transfer and hydrodynamics.The effects of geometric parameters and the properties of solid phase on heat transfer of the structured packed bed were discussed.It was found that at low Re and the same properties and voidage of the packed bed, the larger the specific surface area, the better the ability of heat transfer of the packed bed.Furthermore, the comparison between the simulation results of the metal structured packed bed and heat transfer performance and pressure drop of the pellet packed bed was made, which validated better transport performance of the metal structured packed bed.
