Effect of compaction history on the fluidization behavior of fine cohesive powders
(American Physical Society, 2006)
Fine particles agglomerate in the fluidized state due to the strength of interparticle attractive forces as compared to particle weight. Interparticle adhesion can be largely increased by consolidation stresses applied ...

An automated apparatus for measuring the tensile strength and compressibility of fine cohesive powders
(American Institute of Physics, 2000)
This paper describes an apparatus based on a novel use of a powder bed, whereby the relationship between consolidation stress, tensile strength, and free volume of fine powder is measured. The powder to be tested is first ...

Full-wave analysis of the excitation of magnetostatic-surface waves by a semi-infinite microstrip transducer - Theory and experiment
(Institute of Electrical and Electronics Engineers, 2003)
This paper presents a new method for the complete characterization of the radiation of magnetostatic-surface waves in microstrip transmission lines with longitudinal magnetization. This method is based on the analysis of ...

Dynamics of EHD Laminar Plumes: scaling analysis and integral model
(AIP Publishing, 2000)
In this paper electrohydrodynamic (EHD) plumes are examined in the region far from the injecting electrode and the collector plate, for both two-dimensional and axisymmetric geometries. The relative importance of the ...

Physics of Compaction of Fine Cohesive Particles
(American Physical Society, 2005)
Fluidized fractal clusters of fine particles display critical-like dynamics at the jamming transition, characterized by a power law relating consolidation stress with volume fraction increment. At a critical stress clusters ...
