Abstract
The effect of the mesh refinement and the solid phase boundary condition are investigated for numerical simulation of dense pressurized fluidized bed. Two fluidized beds have been considered: a laboratory-scale device and a pilot-scale facility. A relation is proposed to scale-up the numerical simulation and preserving the spatial resolution accuracy. As expected the boundary condition of the solid phase modifies the behaviour of the fluidized bed. Compared to free-slip wall boundary condition, a no-slip condition improves the numerical predictions with respect to available experimental data.
