visualized induced-charge electrokinetic flow pattern around a carbon-steel sphere (diameter = 1.2 mm). Four induced vortices are shown using fluorescent particles with a diameter of 1.90 μm. The DC electric field is applied from left to right and equals 40V/cm. The dashed line represents the particle boundary.
Electrokinetic phenomena are a family of several different effects that occur in heterogeneous fluids, or in porous bodies filled with fluid, or in a fast flow over a flat surface. The term heterogeneous here means a fluid containing particles.
In general, the phenomena relate to the direct conversion of electrical energy into kinetic energy, and vice versa. In the first instance, shaped electrostatic fields (ESF's) create hydrostatic pressure (HSP, or motion) in dielectric media. When such media are fluids, a flow is produced. If the dielectric is a vacuum or a solid, no flow is ...

The "Biefeld–Brown effect" was the name given to a phenomenon observed by Thomas Townsend Brown while he was experimenting with X-ray tubes during the 1920s while he was still in high school. When he applied a high voltage electrical charge to a Coolidge tube that he placed on a scale, Brown noticed a difference in the tube's mass depending ...
Electrokinetic effects are initiated by sound waves (typically P-waves) passing through a porous rock inducing relative motion of the rock matrix and fluid. Motion of the ionic fluid through the capillaries in the rock occurs with cations (or less commonly, anions) preferentially adhering to the capillary walls, so that applied pressure and ...
Thomas was interested in electronics from early childhood. His wealthy parents indulged their son's interests, buying him experimental equipment. Brown started a lifelong series of experiments with electrical phenomena and began investigating what he thought was an electro-gravity phenomenon while still in high school. [2]
Sedimentation potential. Electrokinetic phenomena are a family of several different effects that occur in heterogeneous fluids or in porous bodies filled with fluid. The sum of these phenomena deals with the effect on a particle from some outside resulting in a net electrokinetic effect.
