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.
