Instability in a non-ohmic/ohmic fluid interface under a perpendicular electric field and unipolar injection
(American Institute of Physics, 2002)
We set the equations for the linear electrohydrodynamic instability of an interface between two fluids, subjected to a perpendicular field and a unipolar charge injection. One of the fluids is modeled as being in non-ohmic ...

Instability of an interface between air and a low conducting liquid subjected to charge injection
(American Institute of Physics, 2006)
We study the linear stability of an interface between air and a low conducting liquid in the presence of unipolar injection of charge. As a consequence of charge injection, a volume charge density builds up in the air gap ...

Modeling the electrophoretic deposition of colloidal particles
(IOP Publishing Ltd., 2001)
This letter presents the results of numerical simulations of the buildup of a layer of colloidal particles on an electrode. In a low-frequency electric field, particles suspended in a low-conductivity liquid migrate to one ...

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 ...

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 ...
