“…The electric field results in a weakly ionized region above the dielectric. The electrochemical interactions between air and plasma lead to complex plasma kinetic phenomena due to coexistence of low density of electrons, positive and negative ions and neutral particles [1][2]. Such plasma discharges produce a wall tangential jet flow [3][4][5][6] due to a self-sustaining process involving high rate of collisions between neutral and charged particle [7][8].…”

Abstract:The natural instability mechanisms are inherent in most of the laminar and turbulent flow configurations. Usually, these instabilities result in the formation of flow structures occurring at diverse spatial and time scales. An effective control requires an actuator able to bring momentum transfer over a wide range of frequency to act on these instabilities. Promising results are expected for such control strategy because, according to stability theory, a small amplitude perturbation can be large enough to produce significant effects even at high Reynolds number. Moreover, simultaneous production of small perturbations at several frequencies can enhance or cancel non linear interactions; this opens alternative methods for flow control. The focus of the present study is to demonstrate the ability of plasma actuators to introduce flow perturbations at single and dual frequencies by simply adjusting the waveform of the voltage applied to the plasma actuator. The flows produced by a dielectric barrier discharge supplied by burst, superposition and ring modulations are described in temporal and frequential domains. The results confirm the potential of non-thermal plasma actuators to produce highly unsteady flows at single, double or multiple frequencies.

“…For all datasets studied, the value of τ obtained by this technique was close to 4 µs and was chosen for the reconstruction of all phase portraits. This behavior might have occurred via a period-doubling bifurcation as the control parameters were changed [23,24]. On the other hand, figure 3(d) shows a complexlooking set of points, a strong argument for the existence of a chaotic attractor in the system.…”

“…In the case of atmospheric-pressure DBD jets, the discharge is generated using a fixed frequency; consequently the system can be considered to be driven. Although chaos in parallel-plate atmospheric DBDs have been proposed theoretically [23,24], its experimental evidence has been reported in only three previous studies [13][14][15]. For chaos in atmospheric plasmas to be fully confirmed experimentally, it is important to employ a range of indicators with more than one observable [25].…”

Abstract:We report detailed characterization of a low-temperature atmosphericpressure plasma jet that exhibits regimes of periodic, quasi-periodic and chaotic behaviors. Power spectra, phase portraits, stroboscopic section and bifurcation diagram of the discharge current combine to comprehensively demonstrate the existence of chaos, and this evidence is strengthened with a nonlinear dynamics analysis using two control parameters that maps out periodic, period-multiplication, and chaotic regimes over a wide range of the input voltage and gas flow rate. In addition, optical emission signatures of excited plasma species are used as the second and independent observable to demonstrate the presence of chaos and period-doubling in both the concentrations and composition of plasma species, suggesting a similar array of periodic, quasi-periodic and chaotic regimes in plasma chemistry. The presence of quasi-periodic and chaotic regimes in structurally unbounded low-temperature atmospheric plasmas not only is important as a fundamental scientific topic but also has interesting implications for their numerous applications. Chaos may be undesirable for industrial applications where cycle-tocycle reproducibility is important, yet for treatment of cell-containing materials including living tissues it may offer a novel route to combat some of the major challenges in medicine such as drug resistance. Chaos in low-temperature atmospheric plasmas and its effective control are likely to open up new vistas for medical technologies.2

“…12,13 These period multiplication and chaos phenomena have been observed in atmospheric barrier discharge in helium and argon. 14,15 However, the characteristics of period-doubling atmospheric dielectric-barrier discharges are still far from clear. A full understanding of these temporal nonlinear behaviors in APGD is critically important in developing techniques to manipulate and enhance the underpinning APGD dynamics for superior plasma stability.…”

Period multiplication and chaos behaviors in atmospheric glow discharges are important to understand atmospheric glow plasma stability and to optimize its applications. In this paper, we study the period-two discharge characteristics in argon atmospheric dielectric-barrier discharges using a one-dimension fluid model. Under certain conditions, period-two discharges can occur at different excitation frequencies and exhibit different current and voltage behaviors. When the discharge current becomes highly symmetrical the period-two discharge can reach to a steady state, which sustains over a broad frequency range. At the sufficiently high excitation frequency, the period-two discharge in atmospheric argon shows noticeably different behaviors from the discharges generated at kilohertz frequency. The spatial characteristics of period-two discharge as well as the influence of driving frequency on period-two discharge behaviors are also investigated.
