同转子尾迹相比,转子叶尖泄漏涡对静子尖区的影响更为明显和深远。
The rotor tip leakage vortex has a stronger influence on the downstream endwall flow than the rotor wake.
动叶尾迹强度明显减弱,叶背流动分离得到抑制,叶尖泄漏涡也得到了周期性的抑制。
The intensity of rotor wakes was reduced, flow separation on rotor suction side was suppressed and the tip leakage flow was suppressed periodically.
最后提出一个重要的组合参数,反映了叶片尖部载荷和叶尖间隙的流向分布对叶尖泄漏掺混损失的综合影响。
Finally, an important combination parameter was put forward to reflect the overall influence of blade loading and tip clearance distribution on the tip leakage mixing loss.
