采用数值模拟方法对某低速压气机静叶根部间隙内的流动结构进行了研究。结果表明,设计工况下,间隙内入口段生成一个中心点结构并快速消散。自35%轴向弦长位置开始,间隙内逐渐生成一系列涡系结构,并在90%轴向弦长位置开始迅速破裂,至95%处全部消散。
Numerical investigation of was done for the flow structure in a compressor stator's hub tip.The result shows that a centre point generates and disappears soon in the fore part of hub tip at design condition.Several vortexes generate from 35% axial chord and break at 90% axial chord,and disappear all at 95% axial chord.
