介质阻挡放电等离子体流动控制研究进展

摘要

Dielectric barrier discharge (DBD) plasma flow control is suited to the low velocity condition. It has a simple structure without mechanical parts, and has thus attracted much attention in research and industry institutions all over the world. DBD plasma flow control has been researched by many scholars in the recent 20 years, and there were a wealth of significant results on both plasma aerodynamic actuation mechanism and applications. In this paper, the physical process of dielectric barrier discharge and the essential mechanism of plasma aerodynamic actuation have been analyzed. Then the DBD plasma flow control, both the aerodynamic actuation mechanism and its applications in recent years, have been reviewed, and the plasma aerodynamic actuation mechanism was generalized in 3 main items. And the paper ends with a discussion about future development of the DBD plasma flow control.%介质阻挡放电（DBD）等离子体流动控制技术适用于低速工况，具有结构简单、动态响应快等优点，受到了国内外学术界及工业界的高度重视．近20年来，很多学者对DBD等离子体流动控制进行了研究，在机理和应用上都取得了很多有意义的结论．本文首先分析了介质阻挡放电及其气动激励基本原理；然后分别对近年来DBD等离子体流动控制机理和应用研究进展进行了综述，并总结提出3个主要气动激励机理：最后对该领域今后的工作提出了几点建议．
