Abstract
Numerous investigations have been devoted towards understanding the hydrodynamics
of particles in fluidized beds. However, most of them paid little to the behavior of
coarse particles inside the fluidized bed. The present work aims to study the influence
of pressure and particle size on the hydrodynamic behavior in fluidized bed processing.
A semicircular fluidized bed, constructed from acrylic glass, with a vertical jet nozzle
located at the centre of the distributor was used in the work. A high speed camera with a
speed up to 3000 frames per second will be used to capture the images of fluidization
process and it will make it possible to track the individual particle motion. The influence of
pressure and particle size on the hydrodynamics can be determined using visualization
by means of high speed photography and video imaging. Therefore the finding of this
investigation will be helpful in understanding the reaction and determining the quality
of fluidization and can be applied to achieve the best process design and optimum
system operation.
