| Abstract: | This review introduces the concept of granular flow, and summarizes the study progress of granular flow in recent years. According to the granular phase being simulated as continuous or not, the methods of numerical simulation are classified into two types, the continuous and the discontinuous models. The discrete element method (DEM) is introduced, which includes hard sphere model and soft sphere model. Through the numerical simulation of granular flow, design and operation of the equipment, such as silo, fixed bed, moving bed and fluidized bed, can be optimized. So it's of great significance for engineering. |
