The influence of the dielectric barrier discharge plasma on the total aerodynamic drag of the Zhukovskii airfoil has been investigated. With the use of the Pitot-Prandtl tube the velocity distribution of discharge-induced ion wind at a distance of 18 mm from the trailing edge of the airfoil has been measured experimentally. It has been shown that the influence of the discharge leads to a decrease in the aerodynamic drag by a value from 10 to 34% depending on the incident flow parameters and the operating conditions of the discharge system.Introduction. The application of the dielectric barrier discharge for controlling the gas flow and its influence on the aerodynamic drag of flying vehicles is now a topical and promising trend in scientific investigations. Important parameters thereby are the velocity of ion wind induced by a near-surface discharge, as well as the structure of the ionized gas flow formed by it [1][2][3][4][5][6][7].The velocity distribution in the near and far wakes behind a streamlined body in the presence of a surface discharge was investigated in a subsonic aerodynamic channel at velocities of 4.6 and 6.8 m ⁄ s [2, 4]. The presented velocity distributions point to a pressing of the boundary layer to the surface near which the dielectric barrier discharge forms a plasma layer, which agrees with the results obtained in [8]. The use of the dielectric barrier discharge plasma permits also solving the problem of gas flow separation from the surface of the wing [9]. The authors of [10] managed to prevent gas flow separation at an angle of attack of 5 o for velocities of up to 2.85 m ⁄ s, and with increasing angle of attack to 15-21 o for velocities of up to 75 m ⁄ s.Because the ion wind velocity strongly depends on the configuration of the system of discharge electrodes, it is difficult to determine what conditions are the most effective in terms of obtaining the maximum velocity of the discharge-induced flow. In the two-electrode system at a distance of 18 mm from the edge of the high-voltage electrode a velocity of ion wind equal to 3 m ⁄ s was registered [6], and the maximum value of the velocity near the needle electrode equal to 6 m ⁄ s was obtained in [1].Setting an additional electrode permits decreasing the space charge accumulation and, as a result, weakening the electric field shielding by charged particles near the discharge electrodes. For these purposes, additional coronaforming or grounded electrodes set in the immediate vicinity of the dielectric surface are used [11]. In the three-electrode system of dielectric barrier discharge formation, a velocity of 4.5 m ⁄ s at a distance of 30-48 mm from the edge of the high-voltage electrode was attained [12].The maximum value of the ion wind velocity at a distance of 18 mm from the trailing edge obtained in the present paper is 1.6 m ⁄ s, which is several times higher than the value equal to 0.35 m ⁄ s given in [12].The results of experimental measurements of the reactive force induced by the ion wind presented by different authors do not ex...

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.

The present study indicates the impact of different arrangements of dielectric barrier discharge (DBD) plasma actuators on temperature field in a channel flow. The modified lumped circuit element electro-static model was used to calculate induced Lorentz body force and plasma dissipation of the actuators. Different distributions of temperature in the modeled channel flow for each arrangement of actuators (one, two, and three attached actuators) are discussed. According to the numerical simulation, DBD plasma actuators are beneficial devices for increasing temperature in the channel flow, especially near the location of the actuators that can be considered for related applications. The actuators are modeled under an incompressible flow regime with a low Reynolds number of 335, and the configurations of the actuators are set to be 3 KV for the peak voltage amplitude, 10,000 Hz for the voltage frequency, and Kapton as the dielectric.
