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.
