Structural reconstruction and levitation of dielectric particle layers in electric fields
Application of an electric field to control the movement of charged particles is widely used in industrial processes.The behavior of a collection of dielectric particles in electric fields is still insufficiently studied.Therefore,we conduct numerical simulations to investigate the full dynamics of dielectric particle layers in an external electric field.Based on the results,the phase diagram for patterns of particle behaviors in an electric field is constructed,and boundaries between adjacent regions are derived.Then,the structure of particle layers is characterized to explore the influence of external field and interparticle electrostatic interactions on the structural reconstruction.Finally,the levitation process of particle layers is analyzed.
