摘　　要：纳秒脉冲表面介质阻挡放电等离子体在高速、高雷诺数下的流动控制领域具有非常大的潜力。文章对纳秒脉冲等离子体流动控制发展的起源、现状和趋势进行了综述。分别从实验研究和数值模拟两方面进行,主要以气动激励机理探索、现象研究以及流动控制机理为主线进行相关文献的总结归纳。目前,纳秒脉冲等离子体研究的关键科学问题集中在电场激励-气动诱导过程的机理探索与流动控制应用机理研究两方面,研究的难点在于涉及多时间尺度、多物理场耦合。注重解决多时间尺度、多物理场耦合问题的数值模拟算法、实验技术将成为解决上述科学问题的关键突破点。关键科学问题的解决有利于为激励器及控制系统的设计提供优化准则。Nano-second pulse surface dielectric barrier discharge （NS-SDBD） has been a topic of great interest in the field of flow control for high speed and high Reynolds number. The recent development tendency of NS-SDBD plasma flow control is reviewed in this paper. The relevant literature of pneumatic excitation mechanism, phenomenon reveal and flow control mechanism is summarized based on experimental investigations and numerical simulations. The key scientific issues of NS-SDBD research are the mechanism of the electric field excitation-aerodynamic induction and the application of flow control. Multiple time scales and multi-physics coupling are the major difficulties of the study. The numerical algorithm and experimental method are generally used for solution of multi-time scale and multi-physics coupling issues. The breakthrough of the key scientific issues contributes to the optimization criteria for the design of the actuator and its control system.
