在本文中，对单个介质阻挡放电（SDBD）等离子体致动器进行了参数研究，以提高其机电性能。研究了三个输入参数：电介质厚度、施加的高压波形和电压转换速率。目标是增加放电引起的电风的速度和/或减少放电的电力消耗。首先，进行了 5 至 30 kV 高压的电气测量，频率设置为 1 kHz。这包括当前记录和电力消耗计算。其次，用皮托管探头测量产生的电风的速度。根据这些速度分布，可以确定最大速度、产生的质量流量和放电的机电效率。它强调，增强这种表面放电机电性能的方法在于使用厚电介质（至少几毫米）和中等频率值的正弦高电压（几十kV）。
In this paper, a parametric study of a single dielectric barrier discharge (SDBD) plasma actuator has been performed in order to enhance its electromechanical performances. Three input parameters have been investigated: the dielectric thickness, the waveform of the applied high voltage and the voltage slew rate. The goal is to increase the velocity of the discharge-induced electric wind and/or to reduce the electrical power consumption of the discharge. First, electrical measurements with high voltages ranging from 5 to 30 kV have been conducted, with a frequency set here to 1 kHz. This consisted of current recordings and electrical power consumption computations. Secondly, the velocity of the produced electric wind has been measured with a Pitot tube probe. From these velocity profiles, the maximum velocity, the produced mass flow rate and the electromechanical efficiency of the discharge have been determined. It highlights that the way to enhance the electromechanical performances of such a surface discharge consists in using a thick dielectric (at least a few millimeters) and a sine high voltage (several tens of kV) at a moderate frequency value.
