摘要
本文采用三维流动数值模拟方法研究了轴流压气机级间环形槽抽气对下游叶排流场的影响。计算表明:抽气使下游叶排S1和S2流面的速度、压力分布以及叶片表面压力分布发生变化;靠近叶顶区域的流场变化尤为明显;随着抽气量的增大,流场受影响程度增大。
The effect of interstage ring bleeding on the flow-field of the downstream row is investigated by the three-dimension numerical simulation. The result shows that the bleeding has made the velocity of downstream stage S1 and S2 flow surface, the pressure distribution and the distribution of pressure on the surface of blade changing. The area close to the blade-tip is affected more distinctly and the more bleeding mass flow, the more it will influence the flow-field.
