Macroscopic behavior of solids circulation in a large jetting fluidized bed was surveyed with a force probe. Particles mixing was studied by pulse injection of tracer particles, and a simple mechanistic model was developed on the basis of the solids circulation pattern observed. The model compares favorably with experimental tracer concentration profiles.
