Research Status of the Flow Model of Powder Particle

The concepts of powder particle and powder particle flow are introduced and two basic types of powder particle flow models,continuous medium model and discrete element model,are summarized.The basic principle is also introduced,and the advantage and disadvantage of the two models and the scope of application are analysed.Through the study of the flow models,the ash bucket and other kinds of engineering equipment can be improved and optimized.So the study has reference for engineering.
