Discharge of turbulent jets into a fluidized bed

Flow Characteristics in a Jetting Fluidized Bed with Acoustic Assistance

“…This conclusion was consistent with the findings of other researchers. [12][13][14][15] As shown in Figure 4, the different investigators employed various fluidized beds with different dimensions, different nozzles with varied inside diameters, different bed materials, and jet velocity. Accordingly, previous papers developed different correlations.…”

“…Up to now, several correlations were developed for predicting the jet penetration depth for horizontal jet on the basis of theoretical analysis and experimental data. 10,[12][13][14][15] With respect to an acoustic fluidized bed, previous articles [16][17][18][19][20][21] reported that an acoustic field can improve the fluidization quality in the fluidized bed. Morse 16 investigated the fluidization behavior of fine particles in an acoustic field and found that, in the sound frequency range of 50-400 Hz and at a sound pressure level (SPL) higher than 110 dB, the channeling and slugging for fine particle fluidization can be suppressed significantly.…”

“…Generally, the jet penetration depth and particle concentration were two of the most important parameters to describe the jetting fluidized bed. Up to now, several correlations were developed for predicting the jet penetration depth for horizontal jet on the basis of theoretical analysis and experimental data. ,− …”
