| Inhoud: |
The hydrodynamic behavior of particles in circulating fluidized beds has been studied by means of a Boltzmann-like kinetic model. Two main regimes of flow: a homogeneous and a heterogeneous regime have been delimited. In the homogeneous regime, for concentrations below a critical value, the flow consists of upward moving solids. Above the critical concentration, clusters appear. Particles velocity distribution at different values of the solid concentration and the ratio of particles being in clusters to those being in homogeneous flow are calculated for different solid mass fluxes, particle size distributions and superficial gas velocities. Slip factors and the effect of gas radial velocity profile have been predicted. Qualitative agreement with experimental data is obtained. |
