Structure of electrorheological fluids [PDF]
The Journal of Chemical Physics, 2000 Specially synthesized silica colloidal spheres with fluorescent cores were used as model electrorheological fluids to experimentally explore structure formation and evolution under conditions of no shear. Using confocal scanning laser microscopy we measured the location of each colloid in three dimensions.

Influence of the Polarity of the Electric Field on Electrorheometry [PDF]
, 2019 Uniaxial extensional flow is a canonical flow typically used in rheological characterization to provide complementary information to that obtained by imposing simple shear flow.

Electrorheological fluids [PDF]
, 1996 An Electrorheological fluid is normally a low-viscosity colloidal suspension, but when an electric field is applied, the fluid undergoes a reversible transition to a solid, being able to support considerable stress without yield. Commercial possibilities for such fluids are enormous, including clutches, brakes, valves,shock absorbers, and stepper ...

The origin of interparticle potential of electrorheological fluids [PDF]
, 2013 The particles of electrorheological fluids can be modelled as dielectric spheres (DS) immersed in a continuum dielectric. When an external field is applied, polarization charges are induced on the surfaces of the spheres and can be represented as point ...

Convergence Analysis for a Finite Element Approximation of a Steady Model for Electrorheological Fluids [PDF]
, 2015 In this paper we study the finite element approximation of systems of $p(\cdot)$-Stokes type, where $p(\cdot)$ is a (non constant) given function of the space variables. We derive --in some cases optimal-- error estimates for finite element approximation

The role of adsorbed water on TiO2 particles in the electrorheological effect
AIP Advances, 2018 TiO2 particles prepared by the hydrolysis of titanium butoxide adsorb water molecules with different adsorption energies. The electrorheological (ER) fluid composed of TiO2 particles behaves as the polar-molecule giant electrorheological (GER) fluid at ...

ELECTRORHEOLOGICAL PROPERTIES OF BIODEGRADABLE CHITOSAN/EXPANDED PERLITE COMPOSITES
Journal of the Turkish Chemical Society, Section A: Chemistry, 2016 In this study, chitosan (CS)/expanded perlite (EP) composites with different chitosan fractions (10%, 20% and 50%) were prepared by absorbing chitosan into porous networks of expanded perlite, as a new hybrid smart electrorheological (ER) material ...

Limit cycle behavior of smart fluid dampers under closed loop control [PDF]
, 2005 Semiactive vibration dampers offer an attractive compromise between the simplicity and fail safety of passive devices, and the weight, cost, and complexity of fully active systems.

Electrorheological fluids [PDF]
The Journal of the Acoustical Society of America, 1990 Electrorheological fluids (ER fluids) are suspensions of fine particles dispersed in an insulating fluid. If the properties of the particles and the fluid are selected properly, the resulting ER fluid can have the remarkable ability to flow like a liquid in its normal state, yet freeze into a gel in an electric field.
