“…the thinner the barrier the higher η E . Such behavior is due to the fact that a thinner barrier corresponds to a larger electrical field between the electrodes, which induces a stronger discharge [23,38,39]. This result is in line with the literature [21].…”

“…Moreover, this expression is true if the discharge does not behave as a filamentary discharge. In the case of thin dielectrics, other authors such as Roth et al (2005) and Enloe et al (2004a) found that:…”

“…7 because the discharge becomes filamentary when the applied voltage is increased, resulting in a power consumption growth. Indeed, the power consumed by the plasma actuator is composed of the power dissipated by the surface discharge and the dielectric losses (Roth et al 2005). As the power losses in the dielectric increase linearly with the voltage frequency and with the square of the voltage (dielectric losses ∝ f AC × V 2 ), the increase in the consumption with a power law higher than two comes from the discharge (see Fig.…”

Sherman 1998). Then, different groups already having background experiences on corona discharges and their interactions with quiescent or moving flows formed a new highly motivated community that contributes to the dissemination of the advantages and relevancy of non-thermal plasma discharges as an alternative to conventional flow actuators (Moreau 2007;Corke et al. 2009Corke et al. , 2010. Rapidly, the number of publications in journals and conference exponentially grows to finally become a full interdisciplinary research field. The sudden interest for surface dielectric barrier discharge (DBD) energized by AC high voltage for manipulating airflows was initially motivated by the easy implementation of these actuators and a possible retrofitting on existing airfoils. They have the capability to be mounted at the surface of linear or curved objects with a minimal protrusion in the flow. Beside, their location can be changed faster than other active actuators that require a new model for each new position of actuation. The amplitude and frequency of the electrohydrodynamic (EHD) force produced by the surface plasma are directly connected to the driven electrical signal, this being a clear advantage for parametric studies on the sensibility of one flow to well-defined perturbations. Indeed, the EHD force (also referred as EFD force for electro-fluid dynamic) and the resulting produced flow called electric wind or ionic wind are due to electric field that acts on charged species. These charged species are produced by physical phenomena such as ionization, recombination, attachment, detachment and photoionization, which occur at timescale of a few picoseconds (Boeuf et al. 2009a). Subsequently, the produced body force, despite being low-pass filtered by fluid mechanical laws (viscosity, energy exchanges, dissipation) to produce electric wind, has a high bandwidth. Plasma actuators, and more specifically dielectric barrier discharge actuators, have demonstrated their authority to Abstract The present paper is a wide review on AC surface dielectric barrier discharge (DBD) actuators applied to airflow control. Both electrical and mechanical characteristics of surface DBD are presented and discussed. The first half of the present paper gives the last results concerning typical single plate-to-plate surface DBDs supplied by a sine high voltage. The discharge current, the plasma extension and its morphology are firstly analyzed. Then, time-averaged and time-resolved measurements of the produced electrohydrodynamic force and of the resulting electric wind are commented. The second half of the paper concerns a partial list of approaches having demonstrated a significant modification in the discharge behavior and an increasing of its mechanical performances. Typically, single DBDs can produce mean force and electric wind velocity up to 1 mN/W and 7 m/s, respectively. With multi-DBD designs, velocity up to 11 m/s has been measured and force up to 350 mN/m.

“…Typically in surface-DBDs the electrodes are deposited on a dielectric slab or embedded in it, and the discharge develops as a thin layer over the dielectric surface [12][13][14][15]. Microscopic optical investigations of such discharges are difficult and scarce, although surface-DBDs have been investigated in connection with O 3 generation and surface treatment, and actually are receiving a growing interest for their possible aerospace application as actuator devices for flow control [15][16][17][18][19]. Therefore the N 2 (A) issue and its relevance in the development of such discharges deserves to be focused.…”

The N 2 (A 3 R u + ) metastable has been investigated in an AC surface dielectric barrier discharge (surface-DBD) at atmospheric pressure in N 2 by Optical-Optical Double Resonance-Laser Induced Fluorescence spectroscopy (OODR-LIF) and by Optical Emission Spectroscopy (OES). The discharge is single-side produced by metallic stripes (comb-like electrode on a dielectric layer). The OODR-LIF measurements have been carried out in space afterglow above the plasma layer. The measurement was time resolved during the AC high voltage cycle and space resolved around the metallic/dielectric stripes. The space afterglow N 2 (A) density does not evidence significant variation in the voltage cycle. The density is higher above the dielectric strip than on the metallic one. N 2 (A) density in the space afterglow has been estimated to be about 10 11 cm -3 . The plasma layer, not accessible by OODR-LIF, has been investigated by OES through NOc and Herman infrared bands. The estimated N 2 (A) maximum density in the plasma layer is higher than 10 12 cm -3 .
