“…The error bar indicates the standard deviation of five repetitive measurements. A time-average body force of 3.0 mN m −1 is acquired at t pw = 211.04 µs, which is slightly higher than that induced by ac-DBD with a similar configuration and electrical parameters (about 2.5 mN m −1 at the peak-to-peak voltage (U p-p ) of 7 kV, the frequency of 4 kHz and the Kapton dielectric thickness of 0.18 mm) [34] but is still two orders less than that induced by the pulsed-DC DBD reported in [35] (300 mN m −1 ). The induced body force increases nonlinearly with the pulsed width.…”

Dielectric barrier discharge using pulsed-DC high voltage (pulsed-DC DBD) have been proven to be capable of effectively reducing skin friction drag in turbulent boundary layers with limited power consumption, thus producing significant net power savings. In this work, the characteristics of pulsed-DC DBD, including power consumption, induced flow structure, thermal effect, and body force, are investigated sequentially. Both the power consumption and pressure waves produced by pulsed-DC DBD are similar to that of DBD using nanosecond pulses (ns-DBD), whereas the wall-bounded jet structure resembles that of DBD using sinusoidal high voltage (ac-DBD). A curved wall jet is induced at a small pulse width, which turns into a straight one due to the combined effect of momentum and thermal addition when the pulse width increases. With increasing pulse width, the induced body force goes up while the thermal effect weakens. Although pulse frequency has no impact on the wall-bounded jet topology, the body force increases with pulse frequency because of the enhanced energy entrainment. With these results, four parameters that affect the performance of pulsed-DC DBD are extracted, including the pulse leading edge, pulse width, frequency, and amplitude, which lays the foundation for the optimization of pulsed-DC DBD.

“…Firstly, the result of P-DC1, which is the same method as used in the previous study (McGowan et al, 2016), is shown. Figure 11 shows the time-averaged flow fields by (a) the Pulsed-DC waveform (calculated from 86 sets of data) and (b) the sinusoidal waveform.…”

“…However, the improvement is only up to about 1.7 times larger in the thrust, and it is not sufficient for the practical use in airplanes and turbines. In 2016, the utilization of Pulsed-DC waveform was proposed by McGowan et al (2016). In their method, a DC power supply is used instead of the AC power supply.…”

Dielectric Barrier Discharge Plasma Actuator (DBDPA) is one of active flow control devices, which generates a wall-surface jet utilizing atmospheric discharge. However, the enhancement of the jet is indispensable for application to high Reynolds number flow because the flow speed is typically only up to several meters per second. In recently, it was reported that a Pulsed-DC voltage waveform can drastically improve the jet thrust (McGowan et al., 2016). In the Pulsed-DC waveform, the high DC voltage rapidly drops to zero and gradually recover. In the original idea, the DC high voltage is applied to the top electrode and the Pulsed-DC waveform is applied to the bottom electrode. In this study, firstly, we conduct experiments using the same method proposed by the previous study, and next, the DBDPA, in which the top electrode is powered by the Pulsed-DC waveform and the bottom electrode is electrically grounded, is investigated. Finally, we propose a new waveform which is a sinusoidal voltage with periodical pulsed-earthing. As a result, the DBDPA with Pulsed-DC voltage waveform cannot generate strong wall-surface jet, and on the other hand, the proposed waveform generates a significant jet. Even though its strength is the same magnitude as that by the simple sinusoidal waveform, it is confirmed that the jet thrust is enhanced at phases before and after the pulsed-earthing; the tentative thrust increment is up to 32 %.

“…Recent experimental investigations reveal that, a SDBD plasma actuator driven by a pulsed-DC voltage waveforms can effectively reduce the skin friction drag reduction in turbulent boundary layers [25][26][27][28][29]. The so-called pulsed-DC SDBD plasma actuators have the same configurations with ordinary SDBD, but the applied voltage waveforms and its applying mode differ: an almost constant voltage was powered on the exposed electrode, while a voltage pulse with a sharp falling stage (< 20 µs) and a very slow rising stage (O(1) ms) was powered on the buried electrode.…”

Surface dielectric barrier discharge (SDBD) actuators driven by the Pulsed-DC voltages are analyzed. The Pulsed-DC SDBD studied in this work is equivalent to a classical SDBD driven by a tailored Fast-Rise-Slow-Decay (FRSD) voltage waveform. The plasma channel formation and charge production process in the voltage rising stage are studied at different slopes using a classical 2D fluid model, the thrust generated in the voltage decaying stage is studied based on an analytical approach taking 2D model results as the input. A thrust pulse is generated in the trailing edge of the voltage waveform and reaches maximum when the voltage decreases by approximately the value of cathode voltage fall (≈600 V). The time duration of the rising and trailing edge, the decay rate and the amplitude of applied voltage are the main factors affecting the performance of the actuator. Analytical expressions are formulated for the value and time moment of peak thrust, the upper limit of thrust is also estimated. Higher voltage rising rate leads to higher charge density in the voltage rising stage thus higher thrust. Shorter voltage trailing edge, in general, results in higher value and earlier appearance of the peak thrust. The detailed profile of the trailing edge also affects the performance. Results in this work allow us to flexibly design the FRSD waveforms for an SDBD actuator according to the requirements of active flow control in different application conditions.
