Magnetorheological Properties of Aqueous Ferrofluids
The nanosized magnetite particles were synthesized by means of a coprecipitation method and used to prepare the aqueous ferrofluids with various volume fractions. The magnetorheological properties of the aqueous ferrofluids have been investigated as a function of magnetic field. Under steady-state shear, the apparent viscosity for all of the ferrofluids exhibited a shear thinning behavior. But ...
متن کاملFerrofluids and Magnetorheological Fluids
Composition, synthesis and structural properties of ferrofluids and magnetorheological fluids are reviewed and compared. The similarities and main differences between the two types of magnetically controllable fluids are outlined and exemplified in the paper. Chemical synthesis and structural characterization of magnetizable fluids for engineering and biomedical applications are thoroughly disc...
متن کاملFerrofluids: Properties and Applications
Magnetic fluids may be classified as ferrofluids (FF), which are colloidal suspensions of very fine (∼ 10 nm) magnetic particles, and magnetorheological fluids, which are suspensions of larger, usually non-stable, magnetic particles. We review the general classification and the main properties of FF, some theoretical models and a few applications. We consider the stability of a FF in terms of v...
متن کاملProperties and Applications of Commercial Magnetorheological Fluids
The rheological and magnetic properties of several commercial magnetorheological (MR) fluids are presented and discussed. These fluids are compared using appropriate figures of merit based on conventional design paradigms. Some contemporary applications of MR fluids are discussed. These applications illustrate how various material properties may be balanced to provide optimal performance.
متن کاملElectrokinetic and viscoelastic properties of magnetorheological suspensions of cobalt ferrite
Magnetorheological suspensions are among the most promising colloidal systems from the point of view of their many potential technological applications. Most studies on these systems have, however, been performed using a non-polar liquid as dispersion medium. In this work we consider aqueous suspensions of synthetic, spherical cobalt ferrite particles. From electrophoretic mobility determinatio...
