| 摘 要： | 实验采用粒子图像测速仪PIV(particle image velocimetry)技术对风力机翼型尾迹的气动干扰进行了研究.针对尾迹对翼型前缘、叶背和叶盆的不同激励,对下游翼碰的流场结构进行了分析.结果表明:有益的尾迹激励为不明显改变下游翼型主流区的非定常激励;当上、下游翼型处于相同攻角和适当轴向距离时,在翼型前缘的...

| Abstract: | The airfoil-wake aerodynamic interaction of wind turbines was experime ntally investigated using PIV(particle image velocimetry) technology.It analyzed the flow structure of downstream airfoil when the wake excited the leading edge,suction side and pressure side of airfoil,respectively.The results indicate tha t the helpful wake excitation is unsteady excitation which doesn't change main flow of downstream airfoil distinctly.The separation area at the suction side is restrained under the wake excitation at ... |
