摘要
介质阻挡面放电(Surface Dielectric Barrier Discharge,SDBD)等离子体主动流动控制技术可以显著改善飞行器的气动性能,已经成为国内外研究的热点问题。通过介绍国外针对SDBD特性、流动控制机理、气动激励数学模型、流动控制影响因素等的研究现状,总结了国内在SDBD等离子体流动控制实验、数值模拟和机理研究方面的进展,归纳出现阶段研究中面临的问题及未来需要解决的问题,并指出提高抑制流动分离能力的等离子体冲击流动控制方式是一种重要研究方向。
Surface Dielectric Barrier Discharge （SDBD） plasma flow control can significantly improve the aerodynamics of aircraft. This technology has become an international hot issue. Status of research on SDBD plasma actuation characteristics, the mechanism of plasma flow control, aerodynamics actuation mathematical model, and influencing factors on the plasma flow control are introduced briefly. Progress of experimental, numerical and mechanism study on SDBD plasma flow control is presented. Brief analysis on the progress of research on the plasma flow control and the problems to be solved in the future are conducted. It is indicated finally that, the pulsed-periodic nanosecond discharge plasma flow control, as called the shock flow control, shows a higher efficiency for controlling the higher-speed flow separation. It becomes an important promising research direction. The research on rarefied gas flow control by plasma should be conducted in the future.
