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.

摘要： 运用计算流体力学（CFD）与计算传热（CHT）方法，对结构化金属填充床内的流体动力学和传热特性进行了详细的模拟，以预测其流场和温度场.分析了床层结构参数和物性的变化对结构化金属填充床传热性能的影响，发现在Re较小且结构化材料和床层空隙率相同的情况下，气固相之间换热的比表面积越大，传热效果越好.进一步将模拟结果与传统颗粒填充床的压降与传热特性进行对照，从而推断结构化金属填充床具有很好的传递性能.
