幼儿园母亲节摘要：An intrusive bioptical probe provides radial profiles of the PDF (probability density function) of the bubble, the cloud, and the emulsion phas behaviors in a fluidized bed of Geldart-A particles. The fluidizing velocity ranges between 0.20 and 0.80 m/s. The bed porosity, the overall averaged bubble chords and velocities are well-predicted by correlations of the literature. The cloud thickness is cloly related to the bubble chord. The amount of gas traveling through the bubble
pha never exceeds 15-20% of the total gas flow rate. The averaged porosity of七星景区
the bubble, the cloud and the emulsion phas is of 88-92%, 65-70%, and 50-55%, respectively. The reduced bubble porosity distribution obeys a constant normal law over the fluidizing velocity range. Each distribution of the reduced bubble chord
