Non-dimensionalization and Three-dimensional Flow Regime Map for Fluidization Analyses

This article is on the dimensional analysis and the classification of fluidization from the viewpoint of numerical analysis. At first, the governing equations used in the DEM (Discrete Element Method) and CFD (Computational Fluid Dynamics) coupling model was non-dimensionalized with the method of He...
