The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



(also electroendosmosis), the movement of a liquid through capillaries or porous diaphragms upon application of an external electric field. It is one of the principal electrokinetic phenomena. Electroosmosis is used to remove excess moisture from the soil in soil compaction for road building and the construction of hydraulic engineering installations, to dry peat, and to purify water and liquids used in industry.

Induced charge electroosmosis flow (ICEOF) phenomenon, which is caused by the interaction between the applied electric field and the electric double layer formed on the polarizable surface, and zeta potential changes on the polarizable solid are shown in Figure 1.
Particle manipulation and fluid flow control using AC electro-osmosis have been reported in various forms, such as biased AC electroosmosis [11, 12], and 3D AC electro-osmosis pump [13, 14], travelling wave AC electro-osmosis pump [15], asymmetric electrode AC electro-osmosis pump [16] and particle traps [17-20].

Seventeen chapters cover basic concepts, governing equations, basic flow solutions, hydraulic resistance and compliance, diffusion, time-dependent flow, capillary effects, electrohydrodynamics, electroosmosis, dielectrophoresis, magnetophoresis, thermal transfer, two-phase flow, complex flow patterns, acoustofluidics, optofluidics, and nanofluidics.
Design-modeling tools are needed that rapidly simulate the complex underlying phenomena such as electroosmosis, electrophoresis, sample dispersion, mixing, and biochemical reactions without significantly compromising accuracy (1-5).
The theoretical aspects of this electrokinetic phenomenon (electroosmosis by Reuss) were formulated in 1897 by Kohlrausch [2].
In situ experiments on low permeability soils provide evidence that pump-and-treat flow rates can be increased using electroosmosis in conjunction with emplacement of granular graphite within hydraulic fractures (Murdoch and Chen 1997).

This process of applying electric current across a saturated soil mass results in electrolysis, transport of species by ionic migration, electroosmosis, and diffusion.
