vortex-ring cascade

In this paper, we mainly discuss the coordinates of vortex in cascade Weis-Fogh mechanism ( degenerate Weis-Fogh mechanism ).

本文主要分析了单翼叶栅型 Weis -Fogh机构 ( 即退化的 Weis -Fogh机构 ) 点涡模型的涡心坐标特点.

In comparison with these of the straight cascade the blade positively curving reduces the quantity of the critical points, eliminates the upper passage vortex, and transform the closed separated flow of the secondary vortex along the blade tip suction side into the open separated flow.

与直叶栅比较，叶片正弯明显减少了壁面与横截面流场中奇点的数量，消除了上通道涡，并使叶顶吸力边的二次涡分离流动由闭式分离转变为开式分离。
