The Dynamics of Fluidized Beds and Granular Flow
Fluidized beds have important technological uses, particularly in petroleum refining, the catalysis of polymers, and combustion. A fluidized bed consists of a vertical chamber containing a layer (bed) of particulate solids that rests on a distributor, though which a liquid or gas is pumped. At sufficiently high flow rates, the particles are suspended (fluidized), and the collective motion of the particles has complex dynamics. The speakers will discuss laboratory experiments and data analysis techniques that are relevant to the characterization of the dynamics of fluidized beds and associated granular flows.
