The scale and strength of passage vortex is also simulated in the flow filed incascade with straight and positively curved blade by using total 3D N-S solver.The results indicate that the passage vortex which is the main part of thesecondary flow can be limited in small-scale steady shape by using curved blade.

借助于全三维N-S方程的求解程序，对直叶片和弯叶片两种流场中的通道涡的尺度和强度进行了数值模拟，模拟结果表明，采用弯叶片可使对二次流起主要作用的通道涡限定在尺度较小的稳定形式上。

When the positive curving angle increases, the total losses of cascades increase, the outlet flow angles vary acutely along the spanwise, the intensity and size of outlet trailing vortex increase obviously, however the intensity and scale of outlet passage vortex vary slightly, secondary flow at both midspan and endwall increase and the total averaged kinetic energy of secondary flow increases..
