N2 - Particle properties are important factors affecting gas fluidization. In the present work, the effects of particle size and shape on the fluidization characteristics are studied using the combined approach of computational fluid dynamics for gas phase and discrete element method for particles. It shows that a bed becomes loosely packed when particle size becomes small. The minimum fluidization velocity increases exponentially with the increase of particle size. Higher minimum bubbling velocities are predicted for ellipsoidal particles compared with spherical ones. Chain phenomenon exists in the expanded and fluidized beds for fine prolate particles.
