To solve this problem, the new discretization technique in the DEM-CFD method is developed, namely the Refined grid model. In the Refined grid model, two different scales of grids are flexibly used: one is for the calculation of void fraction, drag force and buoyancy; the other is for the computation of the fluid equations. Using two kinds of grids, the multiphase flows including thin plates can be calculated in the staggered grids. In the current study, the adequacy of the Refined grid model is proven through the validation tests in the fluidized bed system. Besides, applicability of a scaling law model such as the coarse graining DEM to the Refined grid model is shown for the first time. Consequently, introduction of the numerical simulation techniques is drastically accelerated.
