Mesoscopic structuring and yield stress of magnetofluidized fine particles
(IOP Publishing Ltd., 2009-10)
The fluidization behavior of a bed of fine magnetizable particles excited by an externally applied magnetic field is found to depend on the aggregative nature of the particles before the field was applied. Usually nonaggregated ...

Self-Diffusion in a Gas-Fluidized Bed of Fine Powder
(American Physical Society, 2001)
We have investigated the self-diffusion in a stable gas-fluidized bed of fine powder. Two regimes have been observed: for gas velocities yg above the minimum fluidization velocity ym and below a critical gas velocity yc ...

High viscosity gas fluidization of fine particles: An extended window of quasihomogeneous flow
(American Physical Society, 2006)
We explore the role of gas viscosity in the behavior of gas-fluidized beds of fine powders by means of experimental measurements using nitrogen and neon as fluidizing gases, and theoretical considerations. The existence ...
