Hydrodynamic behavior of circulating fluidized bed with polymeric particles

Effects of external electric field on bubble and charged particle hydrodynamics in a gas–solid fluidized bed

“…According to the experimental results in literatures [43,44], the absolute value of particle charge-to-mass ratio varies from 0.1 to 400 lC/kg. Jiang et al [45] proposed a theoretical model to predict the maximum of particle charge-to-mass ratio, represented as…”

Factors affecting solids segregation in circulating fluidized‐bed riser

“…So far, investigations on solids segregation in the literature (Bi et al, 1992;Bai et al, 1994;Jiang et al, 1994 , 1994) were mainly limited to binary mixtures consisting of coarse and fine particles. The observed segregation patterns are usually presented in terms of fractions of the coarse particles along the riser.…”

“…Most authors have added coarse particles to a circulating fluidized bed of fine particles with a different solids density (Chesonis et al, 1990;Nowak, 1990;Bi et al, 1992: Ijichi et al, 1992Bai et al, 1994;Jiang et al, 1994;Nakagawa et al, 1994). For a mixture of fine particles (FCC.…”

On the electrostatic equilibrium of granular flow in pneumatic conveying systems

“…He argued that the maximum charge dissipation occurs near the upper part of the fluidized bed and the collision of the particles against each other leads to "symmetric electrification," that is, some particles acquire positive charge and others negative charge. Jiang et al 7 applied Gauss's law to spherical particles and calculated a theoretical maximum charge that a particle can carry. They concluded that the maximum theoretical electrostatic charge that can be built up on a particle surface is limited by the breakdown strength of the surrounding fluid.…”
