中文摘要：
为了揭示等离子体气动激励与边界层相互作用的物理机制，作者进行了等离子体气动激励诱导空气流动的PIV研究。实验结果表明：毫秒、微秒等离子体气动激励诱导空气流动以“启动涡”和“壁面射流”的形式出现；当激励电压为12kV时，最大诱导速度约为3m／s；激励电压越大，“启动涡”和“壁面射流”的强度越大；脉冲激励的作用强度和作用范围要强于定常激励。该结论为提高等离子体流动控制的作用能力提供了指导。
英文摘要：
PIV investigation on flow induced by plasma aerodynamic actuation was presented in the paper to reveal the operation mechanism between plasma aerodynamic actuation and airflow. The experimental results show that the flow induced by millisecond and microsecond plasma aerodynamic actuation come out as starting vortex and wall jet. The maximal induced velocity is about 3m/s when the actuation voltage is 12kV. The higher the voltage is, the stronger the starting vortex and the wall jet. The intensity and the influence of the pulse actuation are higher than that of the steady actuation. The results are instructional for increasing the ability of plasma flow control.
