Investigation about Electrorheological Squeeze Film Damper Applied to Active Control of Rotor Dynamic

International Journal of Rotating Machinery, 1997
Electrorheological (ER) fluids, discovered in 1947 by W. WINSLOW, are concentrated suspensions of solid particles in an oily base liquid. Exposed to a strong electric field, their resistance to flow increases very greatly and this change is progressive ...

Electrostatic Force between Two Dielectric Particles in Electrorheological Fluids: beyond Spherical Particles

MATEC Web of Conferences, 2018
In an effort to increase the shear yield stress of dielectric electrorheological fluids, we focus on the electrostatic force of different forms of particles in a dielectric polarization model. By solving Laplace‘s equation and applying the multiple image

Electrorheology of nanofiber suspensions

Nanoscale Research Letters, 2011
Electrorheological (ER) fluid, which can be transformed rapidly from a fluid-like state to a solid-like state under an external electric field, is considered to be one of the most important smart fluids.

A Magnetorheological Fluid Damper for Rotor Applications

International Journal of Rotating Machinery, 2004
Even though we are still far from industrial applications, in the last decade there has been increasing attention directed toward the employment of electrorheological (ER) and magnetorheological (MR) fluids in active bearings and active squeeze film ...

Electrorheological characterization of complex fluids used in electrohydrodynamic processes: Technical issues and challenges

Applied Rheology
The electrorheological (ER) characterization of low-viscosity fluids is paramount for producing micro- and nanoscale products through electrohydrodynamic (EHD) techniques, such as EHD-jet printing, electrospray, and electrospinning.

The Evolutionary p(x)-Laplacian Equation with a Partial Boundary Value Condition

Discrete Dynamics in Nature and Society, 2018
Consider a diffusion convection equation coming from the electrorheological fluids. If the diffusion coefficient of the equation is degenerate on the boundary, generally, we can only impose a partial boundary value condition to ensure the well-posedness ...

The phenomena of electrorheological fluid behavior between two barriers under alternative voltage

Archives of Acoustics, 2004
Electrorheological (ER) fluids placed between two barriers have the ability to change some of their physical properties like the apparent viscosity and modulus of elasticity when an external electrical field is applied.
