The rotor tip leakage vortex has a stronger influence on the downstream endwall flow than the rotor wake.
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 wake is mixing with the last rotor tip leakage vortex in the stator passage, leading to more substantial fluctuations in the flow field.
转子尾迹在静子通道内追赶上从前一转子叶片通道内下来的叶尖泄漏涡，二者的相互作用和掺混导致静子尖区更为复杂的二次流动。
The results show that the performance of optimized fan is improved by lowering the energy loss which caused by the secondary flow vortex, the volute tongue, the wake-jet and the angle of attack.
研究结果表明：通过优化有效降低了因二次流漩涡、风机蜗舌结构、尾流-射流和正冲角等造成的能量损失，提高了离心通风机性能。
