在过去的15年里，利用介质阻挡放电(DBD)等离子体激励器(PAS)对层流边界层进行主动控制已经取得了长足的进步。首先，开创性的实验激励了众多研究人员更深入地了解执行器的基本工作原理和相应的量化性能。这些调查清楚地表明了PA作为流量控制装置的优点，但也显示了其缺点。目前，带有PAS的边界层控制(BLC)经历了从实验室研究到实际飞行应用的过渡。然而，PA社区仍然在为流体机械效率低和执行器有限的动量通量而苦苦挣扎。因此，这篇综述讨论了致动器作为一种节能的流量控制装置在未来飞行应用中的适用性问题。由于任何成功的流量控制都需要对执行器的控制权威有详细的了解，因此本讨论建立在对性能评估措施以及与热力学和运动学环境条件的各种变化的相互作用的仔细而全面的总结的基础上。因此，这篇综述首次在一份连贯的文件中全面讨论了成功的基于DBD的飞行中流量控制所需的所有步骤，从电源到实现流量控制的成功。
Active control of laminar boundary layers with dielectric barrier discharge (DBD) plasma actuators (PAs) has made considerable progress in the last 15 years. First pioneering experiments have motivated numerous researchers to gain a deeper insight into the underlying working principles and corresponding quantification of the actuator performance. These investigations clearly show the strengths but also the weaknesses of the PA as a flow control device. Presently, the boundary-layer control (BLC) with PAs experiences the transition from lab studies to real flight applications. However, the PA community still struggles with the poor fluid mechanic efficiency and the limited momentum flux of the actuator. This review therefore addresses the question how applicable the actuator is as an energy efficient flow control device for future in-flight applications. Since any successful flow control requires detailed knowledge of the actuator’s control authority, this discussion is built upon a careful and comprehensive summary of performance evaluation measures and the interplay with various changes of thermodynamic and kinematic environmental conditions. Consequently, this review for the first time provides a comprehensive discussion of all required steps for successful DBD-based in-flight flow control spanning from the power supply to the achieved flow-control success in one coherent document.
