摘要：

Both the flux of particles ejected from a fluidized bed and the flux of particles entrained above the TDH increase when the bed height increases. Tracer measurements confirmed that jets of particles are ejected from the bed only when two or more bubbles coalesce near the bed surface. A new model which accounts for 'Gulf Streaming' effects can predic the flux of ejected particles.
