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 ...
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.

where ε r is the dielectric constant of the dispersion medium, ε 0 is the permittivity of free space (C 2 N −1 m −2), η is dynamic viscosity of the dispersion medium (Pa s), and ζ is zeta potential (i.e., the electrokinetic potential of the slipping plane in the double layer, units mV or V).
Electro-osmotic flow was first reported in 1807 by Ferdinand Friedrich Reuss (18 February 1778 (Tübingen, Germany) – 14 April 1852 (Stuttgart, Germany)) [1] in an unpublished lecture before the Physical-Medical Society of Moscow; [2] Reuss first published an account of electro-osmotic flow in 1809 in the Memoirs of the Imperial Society of Naturalists of Moscow.
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.
Philippine Studies: Historical and Ethnographic Viewpoints is a quarterly peer-reviewed academic journal covering research on the history and ethnography of the Philippines and its peoples. It is published by the Ateneo de Manila University and was established by Leo A. Cullum in 1953 as Philippine Studies, obtaining its subtitle in 2012. [1]
