The gas-solid flow behavior of a conical spouted bed including heavy particles with density of ρ = 6050 kg/m3 that typically encountered in chemical vapor deposition (CVD) was studied by the CFD technique. An Eulerian-Eulerian two-fluid model (TFM) in conjunction with the kinetic theory of granular flows (KTGF) was used in a full 3D computational framework. To reduce the computational time while maintaining the accuracy of the results, polyhedral mesh structure was utilized. The hydrodynamics parameters including particle velocity and solid volume fraction profiles at different bed levels were evaluated, and the overall behavior of particles in the bed was studied. It was shown that the CFD results agree well with the experimental measurements. Incoherent spouting was also properly predicted by the model, and was shown to be in accordance with the experimental observations.
