Gas-solid flow simulations in spouted beds by using kinetic theory of granular flow

A gas-solid two-fluid flow model was presented, in which the kinetic-frictional rheological model for dense assemblies of solids was incorporated in the spouted bed simulations. This model treats the kinetic and (frictional) stresses of particles additively. The body fitted coordination is used to make the grids best fit the outline of a conical contour of the base in the spouted bed. Calculated particle velocity and concentrations in a spouted bed are in agreement with experimental data.
