Experimental Quantification of the Lateral Mixing of Binary Solids in Bubbling Fluidized Beds

A novel experimental method for the lateral mixing of binary solids in bubbling fluidized beds was developed based on capacitance probe technique. The evolutions local ratios a bed which can be assumed as one cell were analyzed detail. within resolved and effect convection diffusion mechanism evaluated individually. results show that at lower part bed, plays more important role process near wall; meanwhile, is very around center line. This opposite with higher part. micro dispersion coefficient proposed to characterize value generally between 0.005 0.025 m/s. new index evaluate quality solids. It found best acquired half radius, whereas line worst. At part, solid better when increasing distance from wall. influences gas velocity static also discussed microscopic perspective.
