Numerical simulations of effect of particle rotation on gas and solid flow behavior in fluidized beds

Numerical analyses of effect of particle rotation on gas and particles flow behavior were performed using two-fluid flow model combining with the kinetic theory of granular flow. The energy dissipation due to particle rotation is taken into account in the model by the effective inelastic coefficient of restitution. Simulations show that bubbles are more formed in the bed with particle rotation due to the more energy dissipated by rotation. The fluctuations of particle concentrations are more intense due to bubbles motions in the bed. The nonhomogenous flow structure of particles will be evidence considering particle rotation which will be effect the macro-flow structure of particles in the bed.
