摘要
本文采用经过实验校核的数值模拟方法研究了采用正弯静叶的低速压气机内部流动结构。结果表明,由于受片径向力和增强的叶根泄漏流动的作用,正弯静叶流道内的旋涡结构较直静叶明显简化,但考虑到叶片本身的几何形状叶片表面受力的影响,流道出口后的气流掺混较为严重,奇点总数略有增加,旋涡结构相对复杂。
Numerical investigation of flow structure was done in a low speed axial compressor with positive bowed stator passage. With the reasons of radial force of blade and the strengthened leakage flow, the flow structure shows simpler in positive bowed stator＇s passage than the one in straight stator＇s passage. But with the impact of surface force results from complex shape of positive bowed stator, the air flow out of the passage mixes intensely. And it makes the total number of singular points increase and the vortex structure become maro enmnlov
