On Multi-Barrier Plasma Actuators
49th AIAA Aerospace Sciences Meeting including the New Horizons Forum and Aerospace Exposition, 2011The multi-barrier plasma actuator (MBPA) is an extension on the standard dielectric barrier discharge (DBD) actuator which consists of conducting electrodes placed asymmetrically on a single dielectric substrate. The MBPA design incorporates multiple dielectric layers and phase lagged powered electrodes into the standard design in an effort to create a

On Plasma Synthetic Jet Actuators
44th AIAA Aerospace Sciences Meeting and Exhibit, 2006The term plasma actuator refers to an asymmetric arrangement of two electrodes (typically rectangular strips) separated by dielectric material that can be used as active flow control devices. A plasma actuator design consisting of an annular electrode array, the plasma synthetic jet actuator (PSJA), is experimentally investigated in this paper.

Supersonic Plasma and Thermal Actuator
46th AIAA Aerospace Sciences Meeting and Exhibit, 2008In supersonic flows control by thermal and plasma actuators present complex problem because it is necessary to produce vortexes with circulation compared the supersonic flow. Plasma control of supersonic flow is much more difficult problem because of complex plasma chemistry and plasma electrodynamics.

Plasma Actuators for Noise Control
International Journal of Aeroacoustics, 2010In this article the use of plasma actuation for noise control is reviewed. This research follows the tradition of Geoffrey Lilley who conducted the first experiment relevant to aircraft noise, controlling jet noise by disrupting the helical mode of noise radiation.

Performance Improvement of Turbomachinery Using Plasma Actuators
Volume 7: Turbomachinery, Parts A, B, and C, 2011This work deals with the computational modeling of the single dielectric barrier discharge (SDBD) plasma actuator and its applications as a flow actuator. In the literature, plasma actuators have been used especially in order to control boundary layer separation.

Semiconductor enhanced plasma synthetic jet actuator
Journal of Physics D: Applied Physics, 2020Abstract Designing a plasma synthetic jet actuator (PSJA) with high efficiency and low driving voltage is a permanent and unchangeable pursuit for researchers. Based on the surface flashover phenomenon of semiconductors, a novel semiconductor enhanced PSJA (SEPSJA) is put forward.

Turbulent boundary-layer control with plasma actuators
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011This paper reviews turbulent boundary-layer control strategies for skin-friction reduction of aerodynamic bodies. The focus is placed on the drag-reduction mechanisms by two flow control techniques—spanwise oscillation and spanwise travelling wave, which were demonstrated to give up to 45 per cent skin-friction reductions. We show that these techniques

Characterization of Discharge Modes of Plasma Actuators
AIAA Journal, 2008Atmospheric-pressure dielectric barrier discharges for aerodynamic flow control are investigated. The properties of the plasma discharge during positive and negative half-cycles of the driving voltage are studied experimentally and numerically. The simulations are performed in nitrogen.

Aerodynamic actuation characteristic research of array plasma synthetic jet actuator
2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017An array PSJA is tested in this paper by using high-speed phase-lock schlieren system. The characteristic of the transient flow field is studied. The experiment shows that a series of high-speed blast waves spreads outward after discharge. These blast waves, attenuated to the local sound speed, form a wavefront, which continues to influence the flow ...

Numerical Analysis for Plasma Dynamics in SDBD Plasma Actuator
41st Plasmadynamics and Lasers Conference, 20102Time evolution of discharge plasma in the SDBD plasma was simulated by the simplest fluid model; electron and single positive ion species were considered and all volume ionization is the electron-impact ionization. The simulation result in the case of the triangular applied voltage waveform was qualitatively compared with some experimental results ...
