Conductivity in Electrorheology
International Journal of Modern Physics B, 1999Analytical models for the quasi-static ER behavior of suspensions have been developed which take into consideration both the conductivity and dielectric mismatches between the components and the supra-ohmic behavior of the host liquid. Included are models for: (a) slightly conducting particles, (b) insulating particles with a conducting film and (c ...

Electrorheological fluids: structures and mechanisms
Soft Matter, 2008Electrorheology denotes the control of a colloid's flow properties through an electric field. We delineate the basic characteristics of electrorheological (ER) fluids, and show that the use of an effective dielectric constant concept can yield quantitative predictions.

Electro-osmosis of electrorheological fluids
Physical Review E, 2013Electrorheological fluids are suspensions that are characterized by a strong functional dependence of the constitutive behavior of the fluids on the electric field. In this work, we consider electro-osmosis of an electrorheological fluid through a channel where a transverse, nonuniform electric field is spontaneously induced due to the presence of an ...

Continuum modelling of electrorheological fluids
Electrorheological Fluids and Magnetorheological Suspensions, 2002A thermodynamical continuum modelling is proposed for electrorheological fluids. This theormodynamical approach tries to describe the response of an electrorheological fluid in the solid phase (which means with an applied adequate electric field) under mechanical solicitations. Thermodynamic formulations distinguish the contributions due to reversible

Electrorheological Properties of Micro Balloons
IEEE Industry Applications Magazine, 1995In this article, the relation between the densities of particles in electrorheological (ER) fluids and the electrorheological effects was investigated. Micro balloons, used as particles, were dispersed in silicon oil, which was used as the base fluid.

MULTISCALE ANALYSIS OF ELECTRORHEOLOGICAL FLUIDS
International Journal of Modern Physics B, 2002We construct a microscale model for a rigid particle suspension in a viscous fluid that includes Maxwell electrostatic forces. Via homogenization techniques we characterize the properties the material exhibits at the macroscale. The change in the effective constitutive equations is due to the highly oscillating electrostatic forces.

Electrorheological (ER) Fluids
2016Electrorheological (ER) fluids, similar to the MR fluids, belong to the general class of smart materials whose rheological characteristics are identified by applying an electric field instead of magnetic field in MR fluids. In other words, the ER fluids consist of electrical polarizable particles dispersed in carrier fluid with surfactant complimentary,
