  2. Magnetorheological fluid - Wikipedia

    en.wikipedia.org/wiki/Magnetorheological_fluid

    Continuum mechanics. A magnetorheological fluid (MR fluid, or MRF) is a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field, the fluid greatly increases its apparent viscosity, to the point of becoming a viscoelastic solid. [1] Importantly, the yield stress of the fluid when in its active ("on ...

  3. Magnetorheological damper - Wikipedia

    en.wikipedia.org/wiki/Magnetorheological_damper

    Magnetorheological damper. A magnetorheological damper or magnetorheological shock absorber is a damper filled with magnetorheological fluid, which is controlled by a magnetic field, usually using an electromagnet. [1][2][3] This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the ...

  4. Ferrofluid - Wikipedia

    en.wikipedia.org/wiki/Ferrofluid

    Ferrofluid is a liquid that is attracted to the poles of a magnet. It is a colloidal liquid made of nanoscale ferromagnetic or ferrimagnetic particles suspended in a carrier fluid (usually an organic solvent or water). [1] Each magnetic particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ...

  5. Fluid dynamics - Wikipedia

    en.wikipedia.org/wiki/Fluid_dynamics

    t. e. In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids — liquids and gases. It has several subdisciplines, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of water and other liquids in motion).

  6. Thermomagnetic convection - Wikipedia

    en.wikipedia.org/wiki/Thermomagnetic_convection

    Thermomagnetic convection. Ferrofluids can be used to transfer heat, since heat and mass transport in such magnetic fluids can be controlled using an external magnetic field. B. A. Finlayson first explained in 1970 (in his paper "Convective instability of ferromagnetic fluids", Journal of Fluid Mechanics, 40:753-767) how an external magnetic ...

  7. Rheometry - Wikipedia

    en.wikipedia.org/wiki/Rheometry

    Rheometry is a specific concern for smart fluids such as electrorheological fluids and magnetorheological fluids, as it is the primary method to quantify the useful properties of these materials. [citation needed] Rheometry is considered useful in the fields of quality control, process control, and industrial process modelling, among others. [2]

  8. Magnetorheological finishing - Wikipedia

    en.wikipedia.org/wiki/Magnetorheological_Finishing

    Magnetorheological finishing. Magnetorheological finishing (MRF) is a precision surface finishing technology. Optical surfaces are polished in a computer -controlled magnetorheological (MR) finishing slurry. Unlike conventional rigid lap polishing, the MR fluid's shape and stiffness can be magnetically manipulated and controlled in real time.

  9. Damping - Wikipedia

    en.wikipedia.org/wiki/Damping

    In physical systems, damping is the loss of energy of an oscillating system by dissipation. [1][2] Damping is an influence within or upon an oscillatory system that has the effect of reducing or preventing its oscillation. [3] Examples of damping include viscous damping in a fluid (see viscous drag), surface friction, radiation, [1] resistance ...
