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。 In this paper, an experimental verification of the numerical simulation method using a positive curved vane low-speed compressor internal flow structure. The results show that the vortex structure in the positive curved vane flow path is obviously simplified compared with the straight vane due to the radial force and the enhanced leakage of the blade root. However, considering the influence of the blade surface geometry on the vane surface, The airflow after the exit of the runner is mixed more seriously, the total number of singular points slightly increases, and the vortex structure is relatively complicated.
