1) variable curvature cascade
可变弯度叶栅
2) variable camber
可变弯度
3) negatively bowed cascade
反弯叶栅
1.
Experimental results show that negatively bowed cascade produces more energy loss than the straight one without cooling air injection.
对大转折角气冷涡轮直、反弯叶栅出口流场进行了不同位置10排孔喷气及多排孔喷气等26套冷却方案测量。
4) bowed static blade cascades
弯曲叶栅
1.
The control stage of improved 300MW steam turbine used bowed static blade cascades with convergent tip endwall and integral shroud triple pin rotating blades.
优化了 30 0MW汽轮机的调节级 ,采用了子午面端壁收缩的弯曲叶栅 ,动叶为自带围带三销钉三联叶片 ,再用铆接围带形成整圈联结叶片。
5) Curved blade
弯叶栅
1.
The quite detailed information about static pressure distribution near the surface ofconventional straight blade cascades, positively curved blade cascades, negatively curvedblade cascades, all with tip clearance, were obtained.
对具有叶顶间隙的直叶栅、正弯叶栅和反弯叶棚的近壁画静压和出口流场进行了测量,实验结果发现:叶片正弯减小了叶顶中后部的横向压力梯度,削弱了泄漏流与端壁横流及其相互作用,使下游流动损失明显降低;叶片反弯也削弱了泄漏流动,但下游流动损失比其它两套叶栅大。
6) Auto-adjustment blind
可调叶栅
