Gas-solid flow modeling in a spouted bed using discrete element method

Studying particle behavior in a spouted bed usingDiscrete Element Method is the aim of this work. In thisstudy, a numerical simulation using Eulerian-Lagrangian approach is used to solve the Navier-Stokesequations for the gas phase and Newton's laws for thesolid phase to investigate the hydrodynamics of gassolidflow in a spouted bed. The spouted bed studied hasa rectangular cross-section which has been investigatedin recent years because of its advantages in scale-up.The effect of inlet air flow on the creation of a fountainis investigated by applying different air velocities.Effects of higher bed height on increasing the minimumspouting velocity and the bed pressure drop are obtainedand the particle positions are shown at different times.
