Description:
The scaling relationships developed by Glicksman et al. [2] for fluidized beds, have been modified to obtain scaling parameters for a rectangular spouted vessel operated with a draft duct. Similitude included matching the coefficients of restitution and friction of the particles. A CFD model was used to investigate the hydrodynamics of the ''standard'' model and hypothetical ''small'' (1/10th standard) and ''large'' (10x standard) sizes, while matching the dimensionless parameters for the spouted vessel. The results show good similarity at corresponding points for the three different sized vessels. In addition, a correlation is presented that can predict the solids circulation rate to within 17% of the CFD results for units with geometrical similarity to the system investigated.
