For flow control, plasma actuators have the advantages of no moving parts. An experimental study was carried out to generate vortexes using a microplasma actuator. Also, a 3-D numerical simulation code was developed to calculate the flow generated by the microplasma actuator. The numerical simulation used the Suzen-Huang model coupled with Navier-Stokes equations. Our microplasma actuator has a thin dielectric layer with a thickness of 25 μm between the grounded and highvoltage energized electrodes, which enables to drive our device at less than 1 kV. The high-voltage and grounded electrodes have both holes. In the series of experiments, an ac voltage with an amplitude 1 kV and a frequency of 20 kHz was applied to the electrode. The induced flow was visualized using an Nd: YVO4532-nm laser, and the flow velocity was measured using the particle tracking velocimetry (PTV) method. Incense smoke was utilized as a tracer particle. The electrohydrodynamic (EHD) flow was induced around the holes of high-voltage electrode, thus vortexes appeared above these holes. In order to study the basic phenomena of the flow, one and four holes were isolated from the electrode; thus, the phenomena could be observed in a simplified version of the electrode. The 3-D numerical simulation code showed similar results both in values and flow configuration compared with the experimental results.
