  • In recent years coupled DEM–CFD models have been successfully utilized to simulate fluidized particle systems in the bubbling regime. In this paper we report on DEM–CFD simulations of liquid-fluidization of glass beads and gas-fluidization of Geldart's Group A particles carried out to characterize hydrodynamically the stability of the fluidized state, in the absence of cohesive forces. Due to the importance of the fluid–particle interaction, the two-way coupling approach used is introduced… CONTINUE READING
