“…In Equation 8, the inter-electrode gap (g) and dielectric thickness (t) are the next significant parameters, with respective losses of 0.210 and 0.263 mN/m/mm. The loss of thrust with a thicker dielectric agrees with the literature [13,14,15]. Both effects have a comparable amplitude, but there is a measurable difference between the effect of electrode gap and the effect of dielectric thickness.…”

“…At a fixed voltage, Forte et al [13,14] observed that a thinner dielectric thickness increases the maximum velocity induced by the plasma. They also showed that, for a given consumed power, a lower permittivity of the dielectric increases the maximum induced velocity.…”

“…However, the authors highlighted that a thick dielectric of high permittivity can practically sustain higher voltages before reaching breakdown, and hence achieve a greater thrust. Forte et al [13,14] proved a small inter-electrode gap (g) of 0 to 5 mm leads to a greater maximum velocity in the induced wall jet. As a first approximation, Murphy et al [2] noticed an inverse relationship between the consumed power and dielectric thickness (t).…”

The aim of this work is to systematically quantify and rank the effects of nine different design parameters on the fluid mechanic abilities of a Dielectric Barrier Discharge (DBD) plasma actuator supplied with an Alternating Current. The ranking and quantification not only consider the parameters themselves but also their interactions with each other. In order to perform this ranking, a Design of Experiment approach is used. This allows the most significant design parameters for the thrust generation, power consumption and thrust to power consumed ratio (force efficiency) of DBD actuator performance to be determined in a systematic way. The results show that the thrust generation is driven by the voltage, distance between the electrodes, AC frequency, and geometry of the exposed electrode, in that order. A high voltage and high frequency, with a thin dielectric, a narrow inter-electrode gap, and a thin and narrow air-electrode results in an increase in the thrust generation.The thrust to power ratio of a DBD is employed as a proxy for the fluid mechanic efficiency. The analysis of the force efficiency shows that the voltage, frequency, distance between the electrodes, and geometry of the air electrode have significant effects. The higher force efficiency is obtained for a high voltage, low frequency, short inter-electrode gap, thin dielectric of low permittivity with a narrow and thin exposed electrode. Finally, two actuators are investigated to determine the best scaling laws for the power consumption as a function of voltage and frequency. In these experiments, the power consumption was a function of voltage to the power of 2.5 and frequency to the power of 1.5. This systematic study of the parameters and their interactions allows general guidelines to be obtained for the best fluid mechanic performance of a DBD, viz. its thrust generation and force efficiency.

Theoretical analysis of aerodynamic conditions in a plasma chemical reactor with tangential gas supply is carried out. It is shown that due to the creation of a swirling flow in the reactor there is a pressure gradient, due to this along the vertical axis there is a vacuum zone, which contributes to the occurrence of plasma discharge. On the basis of the carried-out experimental researches of plasmolysis of hydrogen sulphide in a swirling stream and the analysis of images of the plasma discharge with use of monochromatic light filters the general structure of the plasma discharge is established. The influence of the temperature gradient in the reactor on the possibility of the formation of sulphur clusters as a prerequisite for the formation of a high molecular weight product – polymeric sulphur – was established.
