转子转动时会产生紊流，就像快艇的发动机产生的尾迹。
As the rotors turn, they generate turbulence, like the wake of a speedboat motor.
由转子尾迹特征参数和紊流度可以求出旋转叶栅损失，为修改设计提供参考依据。
The losses of the rotating cascade determined by the parameters of rotor wakes and the turbulence levels could be used in the design modification.
串列叶栅的尾迹平均速度和紊流脉动速度沿额线方向比单列叶栅变化平缓。
The mean wake velocity profiles behind tandem cascades satisfy the self-similarity, similar to that behind the single-row cascade.
串列叶栅的尾迹平均速度和紊流脉动速度沿额线方向比单列叶栅变化平缓。
Behind the tandem cascades, the variations of mean velocity and turbulence intensity along the tangential direction become more gentle than that behind the single-row cascade.
设计状态转子出口流动阻塞、损失、高水平紊流脉动及噪声主要发生在叶尖通道中部、尾迹和叶根吸力面角区；
In design condition, the flow blockage, loss, turbulence and noise at the exit focus mainly in the tip mid-passage, wake and the corner between the hub and the suction surface;
