Abstract
Gas–particle flow behavior in a conical–cylindrical spouted bed was simulated using the Eulerian–Eulerian two-fluid model. The interaction between gas and particles was modeled by the Gidaspow drag model. The overall flow behavior within the spouted bed was predicted well by the above model. A stable spouted region, a fountain region, an annular region and typical flow characteristics of spouted bed were correctly predicted using the model. Distribution of particle concentration, particle velocity and pressure obtained can provide important information on the flow field within the spouted bed for process design and scale-up. Pressure distribution of simulation was compared with experimental results. The comparative results presented the good agreement.
