1.
From a computation of the three dimensional flow in the first stage in a power turbine,it can be indicated that when tip clearance height is 3 mm,the fluid roll up to form tip clearance vortex at the corner between blade tip and suction surface at about 25% axial chord,resulting in the blockage of main flow.
对某动力涡轮第一级内三维流动的数值计算结果表明,流体在经过动叶叶顶间隙以后在约25%叶顶轴向弦长处(τ=3 mm)在叶顶与吸力边夹角处卷起形成间隙涡,造成流动阻塞,同时在间隙内叶片顶部10%叶顶轴向弦长处(τ=3 mm)开始在压力边出现叶顶分离涡,使得间隙流动损失增加。
2.
Based on the distributions of secondary velocity and averaged azimuthal flow angle, the form of mixing process of tip clearance vortex with passage vortex and its influences on secondary flow structure were studied.

3.
Another more tip clearance vortex appears near the leading edge,which dissipates quickly and keeps the regular one almost near the suction surface.

补充资料：闭锁间隙
闭锁间隙----又叫弹低间隙。武器闭锁后，当枪机与机匣上的闭锁支撑面紧贴，枪弹以斜肩或底沿与枪管紧贴时，枪弹底面与枪机弹底窝平面之间的距离称为弹底间隙。若枪弹底平面与枪机弹底窝平面紧贴，则枪机匣上的闭锁支撑面之间的距离称为闭锁间隙。
