摘要
利用空气中阻挡介质沿面放电等离子体诱导定向气流的特性,创造性地设计多种可用于流动控制的等离子体主动流动控制器;有目的地布置电极,主动组织等离子体诱导的定向气流,形成所需的气体流动结构;对其进行流动显示试验,并采用PIV技术对各新型等离子体流动控制器所形成的流场进行测量。研究结果表明,合理地设计等离子体流动控制器,可以得到所需的流动结构,用于流动控制。本文的研究成果为主动流动控制提供了一类新型的无源流动控制器。
The kinds of new-style plasma flow controllers have been designed to control flow actively accordiHg to the behavior of the directional air flow induced by DBD （Dielectric Barrier Discharge） plasma in still air. The desired flow structures have been obtained by organizing the directional flow induced by DBDplasma through arranging electrodes in the controllers purposefully. The flow fields induced by the new-style plasma active flow controllers have been investigated visibly and measured by PIV. The experiment shows that the required structure of the induced flow can be realized through designing new-style plasma flow controllers reasonably to control flow actively. The research results provide a novel flow controller without flow source for active flow control.
