“…The effect of pulse repetition frequency on the residual surface charge of NS-SDBD was investigated by Peng et al [20]. The influence of the rise time on the discharge characteristics of NS-SDBD was investigated by Xu et al [21], and the results revealed that the shorter the rise time, the greater the discharge intensity and discharge area.…”

There are numerous scientific and engineering fields where the surface dielectric barrier discharge driven by nanosecond pulses (NS-SDBD) has important applications. To improve its performance, more research is still needed on the effects of electrical parameters on the NS-SDBD actuator’s discharge characteristics. In this study, a two-dimensional numerical model based on 13 discharge particle chemical processes was constructed using a numerical simulation approach, producing findings for the NS-SDBD actuator’s voltage–current (V-A) characteristics, discharge profile, and spectrum analysis. Additionally, a comprehensive investigation into the trends and underlying mechanisms of the effects of the voltage amplitude, pulse width, rise time, and fall time parameters on the discharge behavior of the NS-SDBD actuator was carried out. The results show that higher voltage amplitudes increase the maximum current and electron density, which enhances the plasma excitation effect. The peak power deposition during the second discharge is also raised by longer pulse widths and rise times, whereas the total power deposition during the second discharge is decreased by longer fall times.

“…Despite the fact that the computational cost of the fluid-based model is relatively lower, which is potentially realizable for three-dimensional modelling, and it is fully coupled with the Navier-Stokes equations, compared with a physics-based model that considers a kinetics scheme, limitations still appear because it is highly parametric dependent and the evolution of detailed species during the discharge process is neglected. Xu [23] proposed a kinetics scheme of seven species and nine reactions and the effects of configurations of the exposed surface of the driven electrode [24], geometry and waveform of voltages [25] on NS-DBD on a flat surface were investigated. The results show that the reduced electric field of the serrated electrode is the greatest as well as the strength of the compression wave and its propagation speed, while results of the semicircular electrode are the weakest.…”

A curved nanosecond-pulsed dielectric barrier discharge actuator is proposed to fit the flexibly complex surface shape of air vehicles. Streamer evolution and aerodynamic perturbations driven by a single-pulse voltage applied on the anode, where the pulse width is 35 ns and the peak voltage is 14 kV, are numerically studied. Continuity equations that consider 15 species and 34 reactions are solved based on the drift-diffusion approximation. The electron temperature is obtained using the local mean energy approximation method. Discharge characteristics during the voltage-rise, plateau and decay stages are discussed, respectively. The streamer is initiated at 2.2 ns. The maximum electric field is progressively located at the head of the streamer, between the electrodes and in the dielectric layer during the three voltage stages, while the maximum value of electron density is settled at the downstream tip of the driven anode. The electron number density at the streamer head increases at the voltage-rise stage, keeps constant during the voltage-plateau stage, decreases at the beginning of the voltage-decay stage and then increases due to the quenching effect of the excited species. Compared with the discharge on a flat surface, the initial discharge propagation velocity is smaller, while it decreases more slowly during the entire applied voltage. The simulated deposited energy matches the analytical solution well. Aerodynamic perturbations are investigated by solving the compressible Navier-Stokes equations. The ambient air is rapidly heated to the maximum temperature of 1883 K within 0.04 µs. The temperature rise remains greater than 1000 K for 0.32 µs and greater than 500 K for 21.6 µs. A 'semiring-like' compression wave is formed from the discharge region; the propagation speed decreases as it propagates away from the wall and then converges to 345 m s −1 at 13 µs. High-speed flows are rapidly induced at the beginning, and two vortexes are formed successively due to the interaction between the flow induced by the actuator and the backflow induced by the compression wave.

This paper aims to study the effect of different geometrical and electrical parameters, including the voltage, frequency, dielectric thickness, gap width between electrodes, length of electrodes, number of electrodes, and shapes of electrodes, on the induced velocity by the Dielectric Barrier Discharge (DBD) plasma actuators in quiescent air. In addition, the effect of the course of induced velocity evolution in the downstream of actuators has been investigated for different geometries. The streamwise velocity was obtained through the total and static pressure measurement using silicon tubes. The model is a flat plate equipped with a DBD plasma actuator. These experiments were performed for the peak-to-peak voltage range between 8 and 15 kV, and two values of frequency are equivalent to 5 and 10 kHz. The results showed that the multilinear DBD plasma actuator has a maximal induced velocity in the same voltage and frequency as of a single DBD plasma actuator. Evaluation of the induced velocity along the streamwise direction for multilinear, serpentine, and horseshoe actuators showed that these actuators had more than one induced velocity peak.
