“…By converting the heating energy of pulsed arc to gas mechanical energy, PSJA successfully realises the production of high-speed (>400 m/s) high-frequency (>5 kHz) jets, while utilising an acceptable power consumption (0 (100 W)) Narayanaswamy et al 2010;Zong et al 2015a, b;Wang et al 2014). Several evaluation studies on the control authority of PSJA have been performed, such as shock wave manipulation, jet noise mitigation, shock wave boundary layer interaction control and aerofoil trailing edge separation control (Narayanaswamy et al 2012;Emerick et al 2014;Caruana et al 2009Caruana et al , 2013 Abstract This study experimentally investigates the influence of exit orifice shape on the performance characteristics of a three-electrode plasma synthetic jet actuator. High-speed Schlieren imaging system and phase-locked two-component PIV measurements are used for flowfield characterisation in quiescent conditions.…”

“…A pulsed plasma jet inspired by the sparkjet actuator is presented in [14], with a jet velocity of the order of 300 m/s. The ONERA, in collaboration with the CNRS Laplace laboratory (France), is also involved in research into a PSJ actuator [15]. The Laplace laboratory is more particularly interested in the interactions between the power supply and the PSJ actuator.…”

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.

“…A further investigation on the efficiency of such a type of control is thus performed by considering pulsed microjets. It has to be recalled nevertheless that the modelled pulsed actuators do not intend to precisely reproduce the existing plasma synthetic jets developed at Onera (Caruana et al, 2009;Hardy et al, 2010), but are used to illustrate the capacity of the numerical code to reproduce the action of such microjets.

“…Their flow and geometrical characteristics are identical to those used for the continuous microjets; time modulation of the source terms is a periodized crenel, whose value is set to 1 during 1/3 rd of the period and 0 otherwise. This modulation is a first representation of the plasma synthetic jets developed at Onera for flow and noise control (Caruana et al, 2009;Hardy et al, 2010). The two forcing frequencies f F = 3 kHz and 9 kHz are considered for the simulations.…”
