摘要：Biomass energy is considered a promising renewable energy resource to cope with global carbon neutrality goals and the ongoing energy crisis. However, the irregular shapes and varying sizes of milled biomass particles hinder their effective usage in biomass reactors for energy generation. Previous research on non-spherical particles has mainly focused on single-particle systems, with limited studies on binary mixtures. This study employs CFD-DEM method with superquadric shape representation to investigate the mixing behavior of spherical and cylindrical particles in a spouted fluidized bed. The results show that increasing the aspect ratio of cylindrical particles increases accumulation in dead zones. A higher proportion of cylindrical particles significantly reduces spouting height and makes the V-shaped dead zone more evidence. During spouting from a static state, cylindrical particles exhibit notable changes in pitch angle, transitioning from horizontal to vertical orientations, with these trends becoming more pronounced at higher aspect ratios. These findings provide insight into the mixing behavior of binary particle system of spherical and non-spherical particles, and offer a guidance for the reactor operation with these particle types. ? 2025 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences
