Manufacturing of Vortex Granulators: Simulation of the Vortex Fluidized Bed Functioning under the Disperse Phase Interaction in the Constrained Motion

Abstract

The work presents the computer simulation results describing the motion of the interacting particles in a vortex fluidized bed (the constrained motion). The data obtained reveal the peculiar features of the polydisperse system motion in the apparatuses with the variable cross-section of the workspace. The empirical coefficient determining the residence time of a particle in the vortex fluidized bed was calculated. An algorithm of the residence time calculations for a particle in the vortex fluidized bed under the constrained motion is developed. The results of computer simulation were a part of engineering (technological and constructive) algorithm of calculation for the future manufacturing of granulator's industrial sample.
