In order to solve this problem, we developed a Refined Grid Model in DEM-CFD method, where the CFD grid size could be given independently of the particle diameter. This approach is indeed useful in many systems in industries. In this study, the Refined Grid Model was applied to the fluidized bed with a narrow gap channel to show the adequacy of the model. Fluidization conditions in a narrow channel were successfully performed by using this model, though the existing method could not simulate this system. Consequently, it is shown that this model makes it possible to perform a gas-solid flow in a powder system including thin plates.
