摘要：

Research on behavior mode of granular matter under vertical vibration is of great significance in improving the efficiencies of chemical engineering industries. The research has been a popular topic and continuous progresses have been made in this field. The behavior modes of granular matter under vibration were summarized as granular behaviors in a vertically vibrated bed, particle climbing along the pipe inserted in the vertically vibrated granular bed, particle migration in the vibrated U-tube and particle climbing along the vertically vibrated pipe inserted in the static granular bed, and the relevant research progresses were reviewed. It was found that the motion of granular matter was still not well understood and that the mechanism lying in the granular behavior mode remained controversial. Since the discrete element method (DEM) can be used to obtain the information of individual particle motion and thus to well reflect the mechanism and behavior of granular process, the DEM simulations on behavior modes of granular matter both in a vertically vibrated U-tube and in a vertically vibrated pipe were performed to reproduce the experimental results. On this basis, it was proposed that taking advantage of the DEM, the future work should focus on the investigation of the dynamic nature of granular behavior mode and the factors affecting the granular behavior mode in order to provide theoretical foundation and method guidance for the optimization of granular transportation process. © 2016, Chemical Industry Press.
