Hydrodynamics of Jet-Pulsating Mode of Fluidization

“…1(a), which makes it possible to actively form a gas jet. It was experimentally established [1][2][3] that the breakdown height zf of the formed gas jet is 1/3 of the height of the initial bed of solid granular material H0. Therefore, roughly, the velocity of the gas in the slit at point k can be determined from the expression: So, at the gas velocity in the gas distributing device (GDD) slits Wslits=36.6 m/s, the calculated height of the breakdown height of the gas jet accordingly to the experimentally determined gas jet breakdown height (zf=0.085±0.005 m [1]): 0 0.287 .…”

“…For a better distribution of working liquid phase, the authors [2][3][4] proposed the introduction of liquid heterogeneous system during granulation into the middle of the fluidized bed using a mechanical disperser.…”
