“…The S-DBD has a thin structure for plasma generation, thus could limit flow resistance, and is generally used for gas flow control [9][10][11] and gas purification [12] in industrial applications. One of the commonly used configurations is that two electrodes are offset from each other and submerged by the dielectric plate in S-DBDs, [11,[13][14][15][16][17][18][19][20][21][22] as a result, the plasma discharge is performed on one side of the dielectric layer in a single-phase S-DBD. [11,21,23] For the purposes of flow control and gas treatment, increased attention has been put into controlling the plasma behaviors in a singlephase S-DBD.…”

Plasma catalysis is attracting great interest due to its synergistic combination of catalytic and plasma reactor processes. To provide possible controlling methods to this tunability, two‐dimensional particle‐in‐cell/Monte Carlo simulations are applied to investigate the propagation mechanisms of plasma streamers in the porous catalyst in a surface dielectric barrier discharge. Dry air at atmospheric pressure is investigated under a subnanosecond voltage pulse. The results show that the presence of the catalyst pores could enhance the steamer intensity and control the direction of the streamers, yielding highly concentrated reactive species inside catalyst pores. The streamer propagation speed is enhanced by increasing the strength of cathode voltage. These high‐density plasma streamers with controllable direction could benefit many applications in plasma‐enhanced catalysis.

“…Thomas et al [26] measured the thrust and dissipated power using various parameters, including voltage, frequency, electrode width, relative permittivity, and dielectric thickness. The effect of the encapsulated electrode width was evaluated by Qi et al [30], and the effect of the exposed electrode thickness was evaluated by Hoskinson and Hershkowitz [31]. These studies consider the exponents of the voltage and frequency based on the previous studies and analysis the relationship for the structure.…”

Surface dielectric barrier discharge (SDBD) actuators are a type of asymmetric dielectric barrier discharge (DBD) actuator that can be used to generate ions and produce thrust for near-space vehicles. In this paper, a physics-based model for SDBD produced thrust is developed that accounts for geometric and environmental variation between SDBDs. The presented SDBD analytical model (SDBD-AM) is based on models for parallel-plate DBDs but accounts for the "virtual electrode" resulting from changing plasma length that is particular to SDBDs. To validate the model, thrust measurements from twelve different configurations from previous studies were used, and the mean absolute percentage error (MAPE) between each configuration and SDBD-AM was determined. The observed effects on the model were attributed to structural effects including electrode width, electrode spacing, dielectric, and environmental effects including pressure, and the apparent uncertainties are different for each effect. As a result, it was obtained that the MAPE between SDBD-AM and the experimental data for different structures is 11%, and for different pressures, it is 12%. The body force field has been simulated using SDBD-AM and a distribution function in COMSOL software, and the body force profile near the exposed electrode has been validated with a previous numerical model. This model can be used for the design and optimization of SDBD actuators and also in the design of control systems such as spacecraft attitude control in order to increase the accuracy and performance of the controller.

“…The design of an actuator is crucial to the performance of the induced ionic wind. A thick medium, a narrow upper electrode, a wide lower electrode, and a reasonable electrode gap can induce a strong ionic wind for an actuator [31,32]. In this study, the plasma actuator used was composed of two electrodes of the same thickness of 0.06 mm with the electrode gap ∆d of 1mm.…”

Quiescent flow and wind tunnel tests were performed to gain additional physical insights into flow control for automotive aerodynamics using surface dielectric barrier discharge plasma actuators. First, the aerodynamic characteristics of ionic wind were studied, and a maximum induced velocity of 3.3 m/s was achieved at an excitation voltage of 17 kV. Then, the optimal installation position of the actuator and the influence of the excitation voltage on flow control at different wind speeds were studied. The conclusions drawn are as follows. The effect of flow control is better when the upper electrode of the actuator is placed at the end of the top surface, increasing the likelihood of the plasma generation region approaching the natural separation location. The pressure on top of the slanted surface is primarily affected by airflow acceleration at a low excitation voltage and by the decrease of the separation zone at a high excitation voltage. The maximum drag reduction can be realized when the maximum velocity of ionic wind reaches 1.71 m/s at a wind speed of 10 m/s and 2.54 m/s at a wind speed of 15 m/s. Moreover, effective drag reduction can be achieved only by continuing to optimize the actuator to generate considerable thrust at a high wind speed.
