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...
متن کاملManipulation 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...
متن کاملElectrorheological 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...
متن کاملParticle Shape Dependence of Polar Molecule Dominated Electrorheological Effect
We investigated the relations between the yield stress of polar-molecule dominated electrorheological (PM-ER) fluids and the shape of ellipsoidal particles of the fluids. It is found that, when the short axis of an ellipsoidal particle is along an external electric field while the volume of the particle keeps constant, the shorter of the short axis is, the stronger the attraction between the tw...
متن کاملInfluence of liquid phase on nanoparticle-based giant electrorheological fluid.
We show that the chemical structures of silicone oils can have an important role in the giant electrorheological (GER) effect. The interaction between silicone oils and solid nanoparticles is found to significantly influence the ER effect. By increasing the kinematic viscosity of silicone oils, which is a function of siloxane chain length, sol-like, gel-like and clay-like appearances of the con...
