摘要：

A robust three-dimensional discrete particle model (3D DPM) for unstructured meshes is presented to model the gas-solid flows in fluidized beds. Inter-particle interactions are taken into account through a hard-sphere approach. A multifaceted numerical strategy is developed to enhance the computational efficiency. Simulation results demonstrate the ability of the model to capture many important characteristics such as spouting, particle clustering and core-annulus flow structures in gas-solid fluidization systems at specified operating conditions.
