本文介绍了一个参数的实验研究的结果，旨在优化所产生的体积力的单介质阻挡放电等离子体激励器用于气动流动控制。该研究的主要目标是在比以前可能的更高雷诺数下改进用于流控制应用的致动器权限。该研究探讨了电介质材料和厚度，施加的电压幅度和频率，电压波形，暴露的电极几何形状，覆盖的电极宽度，和多个致动器阵列的影响。在每种情况下，用于评估致动器性能的度量是测量的致动器诱导的推力，其与总体积力成比例。它表明，与厚的低介电常数的电介质材料构造的致动器产生的体积力是一个数量级大于由Kapton为基础的致动器在许多以前的等离子体流动控制研究中使用的。这些致动器允许在高得多的施加电压下操作，而不会形成导致体力饱和的离散拖缆。
This paper presents the results of a parametric experimental investigation aimed at optimizing the body force produced by single dielectric barrier discharge plasma actuators used for aerodynamic flow control. A primary goal of the study is the improvement of actuator authority for flow control applications at higher Reynolds number than previously possible. The study examines the effects of dielectric material and thickness, applied voltage amplitude and frequency, voltage waveform, exposed electrode geometry, covered electrode width, and multiple actuator arrays. The metric used to evaluate the performance of the actuator in each case is the measured actuator-induced thrust which is proportional to the total body force. It is demonstrated that actuators constructed with thick dielectric material of low dielectric constant produce a body force that is an order of magnitude larger than that obtained by the Kapton-based actuators used in many previous plasma flow control studies. These actuators allow operation at much higher applied voltages without the formation of discrete streamers which lead to body force saturation.
