“…Recently [29] it has bee found that, varying the amplitude of the high voltage applied to each DBD actuator, the jet can be inclined up to around 20° without any loss in power. Other researches, working with these DBD plasma synthetic jets [30] have found that the angle of the jet could be controlled spanning 180 degrees through small changes in the voltage applied to the electrodes.…”

In this work, we report on electrical and fluid-dynamics studies concerning the flow induced by a sliding discharge (SD). This kind of discharge was created with a three electrode system configuration: one excited with ac and the others with a dc negative voltage. The SD was activated on a quiescent fluid at atmospheric pressure. The flow field induced by the SD was analysed by measurements undertaken with Pitot probes and Schlieren Image Velocimetry. Under the conditions of our experiments two "jet flows", that blown towards the interelectrode space, were induced from the air exposed electrodes. As a consequence of the mutual interaction of these two flows and of the magnitude of each flow, a resulting plume like planar jet of adjustable direction (0-180º) could be formed. A robust control of the axis direction of the plume could be achieved by modifying the ac voltage value.

“…In recent years, various studies have been conducted on electrostatic and electromagnetic actuators. Actuators making use of piezoelectric materials [1][2][3] or plasma [4][5][6][7][8][9][10][11][12][13][14][15] are also being developed. There are several possible configurations for piezoelectric actuators, including: a synthetic jet [1][2] and a flat plat actuator [3].…”

“…This actuator extends the plasma discharge and thus the control surface, when compared with a single SDBD. The SDBD actuator has also influenced new plasma actuator designs, for example a directional micro jet is presented in [10]. The velocity of all of these actuators is less than 10 m/s.…”

Abstract.A promising actuator for high-speed flow control, referred to as a Plasma Synthetic Jet (P.S.J), is being studied by the DMAE department of the ONERA, and the Laplace laboratory of the CNRS, in France. This actuator was inspired by the "Sparkjet" device developed by the Johns Hopkins University Applied Physics Laboratory. The PSJ, which produces a synthetic jet with high exhaust velocities, no active mechanical components and no mass flow admission, holds the promise of enabling high-speed flows to be manipulated. With this high velocity jet it is possible to reduce fluid phenomena such as transition and turbulence, thus making it possible to increase an aircraft's performance whilst at the same time reducing its environmental impact. A thermal plasma discharge was created in a micro cavity, causing the gas to be expelled. It is relevant that the velocity and momentum depend on the energy dispersed by the electric discharge. To control the frequency and energy dispersed in the plasma, the Laplace laboratory has developed two high voltage power supply systems. These allow two different types of discharge to be produced, with energy being supplied to the discharge in two different manners. In this paper, we focus on the impact of the power supply on the Plasma Synthetic Jet, and in particular on the role of the rate of energy dissipation in the discharge. In order to estimate the influence of the power supply on the machinery of the actuator, specific experimental techniques were used to investigate the electrical (voltage, current), thermal (Infra-red camera) and aerodynamic (jet duration, isentropic pressure, jet velocity) characteristics. These data sets were used to determine which of the two power supplies was more effective, thus allowing us to reach several conclusions concerning the importance of the energy dissipation rate on the PSJ actuator.1.

“…Conversely, they have quite low efficiency of energy conversion. Generally, plasma DBD actuators which are powered by alternating current, are used to control in steady regime when instantaneous ionic wind (wall-jet like flow) is produced [3,4,5]. There is also an unsteady regime [6] which occurs after that rectangular modulation is applied.…”

Abstract. The effect of ionic wind generated by plasma actuator on developed boundary layer inside a narrow channel was investigated recently. Since the main investigated plane was parallel to the channel axis, the description of flow field was not evaluated credibly. This paper is dealing with cross-section planes downstream the actuator measured via 3D time-resolved PIV. The actuator position is in spanwise or in streamwise orientation so that ionic wind is blown in the same direction as the main flow or in opposite direction or perpendicularly. The interaction between boundary layer and ionic wind is evaluated for three different velocities of main flow and several parameters of plasma actuation (steady and unsteady regime, frequency etc.). Statistical properties of the flow are shown as well as dynamical behaviour of arising longitudinal vortices are discussed via phase-locked measurement and decomposition method.
