On the entrainment of solid particles from a fluidized bed

Transport Disengaging Height of Iron Ore Particles in a Fluidized Bed

“…erefore TDH data from the previous paper in which particle size distribution was given switched TDH of smallest particle of the bed. e dependency of the experimental variables on the TDH can be expressed as In previous studies, the TDH was correlated in terms of a dimensionless parameter such as Reynolds, Froude and Archimedes number (Soroko et al, 1969;Yoon et al, 1986;Ściążko et al, 1991).…”

Elutriation and agglomerate size distribution in a silica nanoparticle vibro-fluidized bed

“…It should be noted that, when the height above which the concentration of entrained particles remains constant or varies only slightly, this height is referred to as transport disengaging height (TDH) [47]. In this work, the elutriation measured as a total mass loss of the bed material, thus it represents the elutriation above the TDH.…”

Computational analyses for modeling fluidized bed gasification processes

“…No common trend is found for the experimental conditions.
