The experiment results show that using non-smooth blades can change the exit streamwise vortex structures. The exit flow fields tend to well-distributed. The overall blade losses are reduced.
实验结果表明，采用非光滑叶片改变了叶栅出口旋涡结构及流动分布，使叶栅出口的流场趋于均匀，叶片可以随更大的负荷。
The advanced small gasturbines feature small mass flow ratio, short vanes and blades with low aspect, high second flow and blade tip leakage losses, and low efficiency.
先进的小发动机涡轮的流量小，叶片短，展弦比低，二次损失及叶尖漏泄损失大，效率低，温度高冷效差。
For the turbine stator cascade, the negative curving of blade can not improve the performance of the cascades as well, the total losses of straight cascade are the lowest.
叶栅中部和端部二次流均增强，总平均的二次流动能增大。对于该叶栅，叶片反弯曲亦不能提高叶栅流场的气动性能，直叶片叶栅总损失最小。
The combination of the slot with an optimized blade design significantly reduces the secondary flow losses compared to the original turbine stator, especially at large negative angles of incidence.
经联合造型后的叶栅与原始叶栅相比在各个攻角下的流动损失均有大幅度降低，大负攻角下效果尤为明显。
The most affected was secondary flow losses for the energy loss distribution along the blade height, other losses along the distribution was average.
对于能量损失沿叶高分布影响最大的是二次流损失，其他损失沿叶高分布相对比较平均。
Under high velocity flow conditions, cascade losses are mainly caused by radial drift of the boundary layer along the suction surface and by blade wakes.
在高速流动条件下，叶栅损失主要是吸力面边界层径向串流及其尾迹。
Although the electrodes are installed along the whole blade height, the plasma merely reduces the losses in the region above 10% blade height, and the loss reduction is almost the same in this zone.
虽然电极沿整个叶高方向布置，但等离子体仅对约10%叶高以上的损失影响较为明显，同一电压下该范围内各叶高处的损失减小量也基本相同。
