Abstract: The paper presents a computational study of the gas-solid flow in a
three-dimensional spouted bed by a combined approach of discrete element method and
computational fluid dynamics (DEM-CFD), in which the motion of individual particles was
obtained by solving Newton's second law of motion and gas flow by the Navier-Stokes equation
based on the concept of local average. The coupling between the discrete particle and continuum
gas was achieved by applying the principle of Newton's third law of motion. It was shown that
the motion of particles was forming a distinct circulation between center zone and boundary
zone of the 3D spouted bed in macro, and there was a stagnant zone near the bottom of the bed
in which the particle velocity is almost zero near the wall, they do not move anywhere. The
