Particle motion in a rotating fluidized bed was studied by obserยฎing the mixing of two layers of particles of different colors. The particles in the two layers were either nearly identical, except for their color, or were of different density and size distribution. All of the particles were in the G

Abstract
Trajectories of bubbles and entrained particles in the rotating fluidized bed were obtained from equations expressing a balance among inertial, centrifugal, Coriolis, gravity and drag forces. The solutions led to information on the behavior of isolated bubbles, bubbles swarms and the elutriation characteristics of the rotating fluidized bed.

## Abstract Modeling and measurement of bubble size in a rotating fluidized bed (RFB) is described. A novel model of bubble growth has been proposed based on a bubble coalescence model by Darton et al. We modified the model according to the following concepts: (i) local centrifugal acceleration and
However, the bubbling up vapor flows just through the downcomer bottom-orifices. The vapor occupies the part the of orifice area, so the orifice area for liquid descending is reduced and the downcomer liquid height increases which causes a premature downcomer flood as well. Moreover, the orifice are
