Dynamic polarizability of rotating particles in electrorheological fluids.
A rotating particle in electrorheological (ER) fluid leads to a displacement of its polarization charges on the surface which relax toward the external applied field E0, resulting in a steady-state polarization at an angle with respect to E0. This dynamic effect has shown to affect the ER fluid properties dramatically. In this paper, we develop a dynamic effective medium theory (EMT) for a syst...
متن کاملDielectric Properties of Electrorheological Fluids Containing Zeolite Particles
Relationships between electrorheological (ER) effects and dielectric properties of suspensions are investigated from measurements of ER and dielectric properties of suspensions containing particles of type A zeolite such as 3A, 4A and 5A. In each suspension containing zeolite 3A or 4A particles, the ER effect is recognized, I.e., an increase in the apparent viscosity is observed when an electri...
متن کاملDynamic dielectric response of electrorheological fluids in drag flow.
We have determined the response time of dilute electrorheological fluids (ER) in drag flow from the dynamic dielectric response. On the basis of a kinetic rate equation a new formula was derived to approximate the experimental time-dependent dielectric permittivity during the temporal evolution of the microstructure. The dielectric response time was compared to the standard rheological response...
متن کاملStructure of electrorheological fluids
Specially synthesized silica colloidal spheres with fluorescent cores were used as model electrorheological fluids to experimentally explore structure formation and evolution under conditions of no shear. Using Confocal Scanning Laser Microscopy we measured the location of each colloid in three dimensions. We observed an equilibrium body-centered tetragonal phase and several non-equilibrium str...
