Compressible magnetorheological fluids

Journal of Applied Polymer Science, 2009
AbstractA novel compressible magnetorheological fluid (CMRF) has been synthesized with additives that provide compressibility to the fluid. This CMRF has been designed to provide an elastic component to a magnetorheological fluid (MRF) that can be used as a springless damper. CMRF provides controllable compressibility to the MRF. The controllability of

Magnetorheological fluid composites

Journal of Physics D: Applied Physics, 1996
An interesting extension in the use of magnetic fluids has resulted from the development of magnetic fluid composites obtained by dispersing micrometre-sized non-magnetic particles in a magnetic fluid. The composites possess a yield stress in a magnetic field which can be described at sufficiently high strain rates by the Bingham relation , where is ...

IRREVERSIBLE EFFECTS IN MAGNETORHEOLOGICAL FLUIDS

Electro-Rheological Fluids and Magneto-Rheological Suspensions, 2011
The effect of residual structure on properties of MR fluids, based on CI particles, was investigated using a magneto-sweep technique and initial magnetic susceptibility measurements. The shear rate, particle size, and the CI surface properties were among the experimental variables.

Fluid Flow Control Using Magnetorheological Fluids

SPE/DOE Improved Oil Recovery Symposium, 2002
Abstract Magnetorheological fluids (MRFs), i.e. suspensions of ferri- or ferromagnetic particles in a water or an oil-based carrier fluid, stabilized by a surfactant or polymer, are deemed suitable for fluid flow control in oil and gas recovery operations.

Magnetorheological Fluid-Based Seal

Journal of Intelligent Material Systems and Structures, 1996
The present experimental work has been done to study the characteristics of the simplest one-step magnetofluid seal (MFS) of the rotary shaft in which the MR fluid (MRF) serves as a sealing medium. The experiments show that the characteristics of the MRF-based seal differ very much from those of the ferrofluid (FF)-based one.

Flow of Magnetorheological Fluids

Journal of Intelligent Material Systems and Structures, 2001
For efficiently describing the flow of magnetorheological fluids (MRFs), a feasible model based on the Bingham equation is presented. It allows the determination of rheological parameters from parameters attained with a measuring equipment working in the flow mode.

Magnetorheological fluids: a review

Soft Matter, 2011
Magnetorheological (MR) materials are a kind of smart materials whose mechanical properties can be altered in a controlled fashion by an external magnetic field. They traditionally include fluids, elastomers and foams. In this review paper we revisit the most outstanding advances on the rheological performance of MR fluids.

Magnetorheologic fluids for actuators

Sensors and Actuators A: Physical, 2001
Abstract Magnetorheologic fluids (MRF) are suspensions consisting of a synthetic oil and very small soft-magnetic particles. In a magnetic field, the particles are locked to long chains. In consequence of it, the viscosity and the flow behaviour of the fluid are considerably changed.

Introduction to Magnetorheological Fluids

2023
Magnetorheological fluids are multiphase magnetizable suspensions with magnetic field-controllable mechanical properties. In this introductory chapter we revisit the physics behind the rheological response of these particular materials making special emphasis on the influence of magnetostatic and hydrodynamic forces.
