Abstract: | Most hydrodynamic fluidized bed models,including CFD codes,neglect any effects of the plenum chamber volume.Experiments were performed in a 0.13 m ID fluidization column to determine plenum chamber volume effects on fluidized bed hydrodynamics for FCC and glass particles.Two low-pressure-drop distributors were used,one with a single orifice,and the other with 33 orifices and the same total open area as the single orifice.The results show two peaks in the frequency spectra for the single-orifice distributor,... |
