摘要：
In this paper, the mechanisms of particle movement on an electric curtain are examined. Intermittent bursts in which particles leaping from a surface of an electric curtain are demonstrated both by numerical simulation and experimental observation. The hopping and surfing modes during particle removal are shown to depend on the particle electric charge and its initial position. The particles initially located on the top of electrode have a large electric charge tend to assume a hopping mode. Transverse movement of the particle initially located between the electrodes is analyzed, and the particle traps along the electric curtain surface are also observed.
