Abstract
An analytical approach is given for the electric current and attractive force between spherical dielectric particles surrounded by a conducting film and situated in a nonpolar liquid. Good agreement occurs between the calculated values and those measured on humidified glass beads in silicone oil. Also, the model predicts a decrease from a quadratic electric field dependence of the force as the field strength is increased, in accord with the results for many electrorheological fluids. The effects of certain parameters which govern the conductivity of the host liquid and of the particles are considered.This publication has 3 references indexed in Scilit:
