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 ...

Structural explanation of the rheology of a colloidal suspension under high dc electric fields
(American Physical Society, 2006-04-07)
In this work we describe the electrorheology of suspensions consisting of hematite ( α − Fe 2 O 3 ) particles dispersed in silicone oil in the presence of large dc electric fields. If an electric field pulse is ...

Electromechanics of fluidized beds of nanoparticles
(American Physical Society, 2009)
The electromechanical behavior of a gas-fluidized bed of insulating silica nanoparticles is investigated. When fluidized by gas, these nanoparticles form highly porous agglomerates of size of the order of hundreds of ...

Magnetofluidization of fine magnetite powder
(American Physical Society, 2009)
The behavior of a fluidized bed of fine magnetite particles as affected by a cross-flow magnetic field is investigated. A distinct feature of this naturally cohesive powder, as compared to noncohesive magnetic grains usually ...

Nanofluidization electrostatics
(American Physical Society, 2008)
Electrostatic charging of powders is a relevant phenomenon for a number of industrial applications. The design of new processes and the use of high resistivity materials and ultrafine powders may lead to higher charging ...
