This study investigated the effect of the alternating electric field conditions on the generating mechanism of the specific structures of the particle dispersion type functional fluid, which consists of suspended micro scale diamond particles in insulated silicon oil. These specific flow structures contribute actively to a polishing process and to the development of micro fluidic devices. One of the specific flow structure is rotational flow structure formed under high-electric-field intensity and low-frequency conditions. This rotational flow structure is induced by the local accreted flows indicated as the characteristic velocity. The electric field waveform and frequency affects the movements of the local accreted particle that induce the accreted flow between the electrodes. The working time of the electric field is important to generate the accreted flow and the inclination of the electric filed dose not contribute to generate the accreted flow.
