Abstract

A numerical scheme based on the distributed Lagrange multiplier (DLM) method is used to simulate the process of separation of particles with different dielectric properties suspended in an electrorheological (ER) fluid and subjected to a nonuniform electric field. The dielectrophoresis induced separation of particles is possible only when the sign of Clausius-Mossoti factor for the particles is different, as in this case the dielectrophoretic force moves them to different regions of the device. The time required for separation of particle in simulations is larger than that given by an order of magnitude analysis because of the formation of particle chains which arise due to the dipole-dipole interactions among the particles and move much more slowly than isolated particles.
