Dynamic simulation of an electrorheological fluid

Electrorheological fluid dynamics.

We use the Onsager principle to derive a two-phase continuum formulation for the hydrodynamics of the electrorheological (ER) fluid, consisting of dielectric microspheres dispersed in an insulating liquid. Predictions of the theory are in excellent agreement with the experiments. In particular, it is shown that whereas the usual configuration of applied electric field being perpendicular to the...

Dynamic Simulation of an Industrial Rotary Dryer

Manipulation of microfluidic droplets by electrorheological fluid.

Microfluidics, especially droplet microfluidics, attracts more and more researchers from diverse fields, because it requires fewer materials and less time, produces less waste and has the potential of highly integrated and computer-controlled reaction processes for chemistry and biology. Electrorheological fluid, especially giant electrorheological fluid (GERF), which is considered as a kind of...

Finite Element Simulation of Electrorheological Fluids

Electrorheological (ER) fluids change their flow properties dramatically when an electric field is applied. These fluids are usually composed of dispersions of polarizable particles in an insulating base fluid or composed of liquid crystal polymer. To build more suitable and complicated designs for application of ER fluid, the simulation of ER fluid as well as experiments are important. First, ...

Electrorheological Fluid Based Force Feedback Device

Force feedback from remote or virtual operations is needed for numerous technologies including robotics, tele-presence, teleoperation (e.g., surgery, etc.), games and movies. To address this need, the authors are investigating the use of electrorheological fluids (ERF) for their property to change the viscosity under electrical stimulation. This property offers the capability to produce feedbac...
