Particle-tracking studies for solids motion in a gas fluidized bed
The present study concerns the development of a technique, based on radioactive particle tracking, to study the solids motion in fluidized beds. The mean velocity distributions of solids, ranging from 0.42 and 0.8 mm, fluidized by air flows, ranging from 1.65 to 4.6 times the minimum fluidizing velocity, are presented. Several exploratory studies were conducted. Sample results of the Lagrangian auto-correlation and turbulent shear stress of the fluctuating velocities are presented. Furthermore, by superimposing selected sets of the tracer's location data to synthesize the stratified bed experiments, a picture of the solids mixing was obtained. The results suggest that they are feasible and could be valuable in furthering the understanding of fluidized bed dynamics.
