by which the fluid-particle interaction can be simulated more accurately. The simulation results presented the packing voidage distributions and the air flow fields in the sinter beds of different single and mixed particle size ranges. The bed pressure drops were simulated and the results were compared with the corresponding experimental ones. The good agreement indicated that the proposed resolved CFD-DEM method is an effective tool to model the fluid-particle interaction for irregular large granules in the gas-solid multi-phase systems.

Xing Liu， Bruce D. Hammock IssueVolume: 2024/01/12 Abstract: A resolved CFD-DEM method is proposed to simulate the fluid-particle interaction for large complex granules. The air flow in a vertical sinter fixed bed is numerically studied using this method. The multi-sphere clumped method is used to create irregular sinter particles in DEM. The immersed boundary method and dynamic cell refinement are applied to describe the fluid flow around particles with higher resolution，用该方法对垂直烧结固定床内的气流进行了数值研究， 模拟结果显示了不同单粒径和混合粒径范围的烧结床中填料空隙率分布和空气流场，采用浸入边界法和动态单元细化方法，从而更准确地模拟流体与颗粒的相互作用， Zongwen Tang，创刊于2003年， 附：英文原文 Title: Coupled simulation of fluid-particle interaction for large complex granules: A resolved CFD-DEM method for modelling the air flow in a vertical fixed bed of irregular sinter particles Author: Benchao Su，对床层压降进行了模拟。
