Study on Electrorheological Characteristics of Polythiophene-based Electrorheological Fluid

Electromagnetic Materials, 2005
Electrorheological (ER) fluids are typically composed of polarizable particles dispersed in a nonconducting fluid. Upon the application of an electric field, chain-like or fibrillar aggregates of the suspended particles are oriented along the direction of the electric field, thereby inducing viscoelasticity and a drastic increase in viscosity.

Conductivity in Electrorheology

International Journal of Modern Physics B, 1999
Analytical 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 ...

Boundary effect in electrorheological fluids

Physical Review E, 2011
The effect of the boundary friction coefficient on the rheological properties of the electrorheological (ER) fluids in quasistatic and dynamic states is investigated by computer simulation. The relation between the shear stress and the boundary friction coefficient in quasistatic and dynamic states is discussed qualitatively and quantitatively, and the

Electrorheological Properties of Micro Balloons

IEEE Industry Applications Magazine, 1995
In 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, 2002
We 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.
