[1] [2] [3] There is a common source of all these effects—the so-called interfacial 'double layer' of charges. Influence of an external force on the diffuse layer generates tangential motion of a fluid with respect to an adjacent charged surface. This force might be electric, pressure gradient, concentration gradient, or gravity.
Electrokinetic phenomena, a family of several different effects that occur in heterogeneous fluids; Zeta potential, a scientific term for electrokinetic potential; Electrokinetic remediation, a technique of using direct electrical current to remove particles from the soil; Electro-kinetic road ramp, a method of generating electricity
Electrohydrodynamics (EHD), also known as electro-fluid-dynamics (EFD) or electrokinetics, is the study of the dynamics of electrically charged fluids. [1] [2] Electrohydrodynamics (EHD) is a joint domain of electrodynamics and fluid dynamics mainly focused on the fluid motion induced by electric fields.
The electrokinetic phenomenon was observed for the first time in 1807 by Russian professors Peter Ivanovich Strakhov and Ferdinand Frederic Reuß at Moscow University, [4] who noticed that the application of a constant electric field caused clay particles dispersed in water to migrate.
[3] In 1942, the Long Island Biological Laboratories research project, headed by Harold Abramson, was established in part with funds from the Josiah Macy Jr. Foundation and support from the War Department. Abramson was then a Major in the Technical Division, Chemical Warfare service of the United States Army. [4]
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.
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 ...
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.
