Effects of particle size and field orientation on the yield stress of magnetostabilized fluidized beds
(American Chemical Society, 2012-05-23)
In this work, we present experimental measurements of the yield stress of gas-fluidized beds of magnetizable particles stabilized by an externally imposed magnetic field. Powder samples consist of spherical magnetite ...

Fluidization of nanopowders: a review
(Springer Verlag, 2012)
Nanoparticles (NPs) are applied in a wide range of processes, and their use continues to increase. Fluidization is one of the best techniques available to disperse and process NPs. NPs cannot be fluidized individually; ...

Magnetic field induced inversion in the effect of particle size on powder cohesiveness
(AIP Publishing, 2010-07)
Experimental measurements are reported on the tensile yield stress of magnetofluidized beds of fine magnetic powders operated in the cross-flow configuration. In the absence of externally applied magnetic field the yield ...
