| 摘 要： | 在低速开口风洞中进行了等离子体激励器对NACA0015翼型流动分离控制的实验研究。采用PIV技术,对翼型绕流流场进行了测量,显示了施加等离子体激励后流场的变化。通过五分量天平对升力和阻力的测量,研究了激励电压和激励频率对翼型流动分离控制的规律。研究表明,低风速下在翼型前缘施加等离子体激励,能够有效地控制翼型流动分离,在来流为20 m/s时,最大升力系数增加11%,失速迎角增加6°;在给定的流动状态下,激励电压和激励频率存在一个阈值,不同迎角下该阈值不同,迎角越大,分离越严重,对激励强度的要求也越高。

| Abstract: | Influence of plasma actuators on the flow separation control of NACA 0015 airfoil was investigated in an open-circuit low-speed wind tunnel.Particle Image Velocimetry(PIV) technology was applied to visualize the modification of the flow structure over the airfoil by the plasma actuators.Lift and drag were measured by a five-component strain gauge balance to investigate the separation control effect of the actuator voltage and excitation frequency.The results show that the leading-edge plasma actuators are e... |
