摘　　要：本文利用尖劈和粗糙元在低速风洞内生成了具有高风速和高湍流强度特征的热带气旋大气边界层,并测量了热带气旋作用下风力机模型后不同流向位置处的尾流特性,发现距离转子越远,尾流区内轴向速度亏损和湍流强度越小;距离转子6R位置处风力机尾流基本恢复,原因在于高入流湍流强度的影响。The atmosphere boundary layer of tropical cyclone in wind tunnel was generated with spires and roughness elements which had high speed and high turbulent intensity.The characteristics of wake behind wind turbine model were measured with hot wire anemometer.The velocity deficit and turbulent intensity would decrease with the increase of distance from the wind turbine and the wake had already recovered when the distance was six times the radius.
