Abstract
A basic research is being carried out on the transport of particles in electrostatic traveling field. A particle conveyor that consists of parallel electrodes was constructed and four-phase traveling electrostatic wave was applied to the electrodes. The following were clarified by experimental and numerical investigations: (1) The mode of particle transport was classified into four: passing region that the transport speed was higher than the wave, synchronous region that particle motion was synchronized with the wave, backward region that particles moved backward to the wave, and vibration region that particles only vibrated but not transported. (2) Numerical 'calculation was conducted based on the three-dimensional Hard Sphere Model. Calculated results qualitatively agreed with experiments.
