等离子体对翼型流动分离控制历程的PIV试验研究

PIV measurement on airfoil flow separation control course by plasma actuation

  • 摘要: 采用粒子图像测速(Particle Image Velocimetry,PIV)技术,研究了介质阻挡放电等离子体激励对NACA0015翼型表面流动分离的控制特性及控制效果随时间历程的变化规律.结果表明,激励电压存在一个阈值,当电压小于阈值时,控制无效或效果不明显;当电压接近阈值时,控制表现出不稳定性并最终趋于稳定;当电压大于阈值时,控制效果稳定且显著,气流能够很好地重附在翼型表面.
