【摘要】：正角区分离是轴流压气机中普遍存在的一种流动结构,尤其是在非设计工况下,角区分离会导致压气机效率降低,增压能力下降。针对这一问题,中国科学院工程热物理研究所的研究人员采用平面叶栅实验与三维CFD(计算流体力学)数值模拟相结合的方法,对压气机典型工况下的角区分离流动结构,以及损失特性进行了深入研究。
[Abstract]:The separation of positive angle region is a common flow structure in axial flow compressor, especially under non-design conditions, the separation of angle region will lead to the decrease of compressor efficiency and the decrease of supercharging capacity. In order to solve this problem, the researchers at the Institute of Engineering Thermophysics of the Chinese Academy of Sciences adopted the method of combining plane cascade experiment with three-dimensional CFD (Computational fluid Dynamics) numerical simulation to separate the flow structure in the angular region of the compressor under typical working conditions. And the loss characteristics are deeply studied.
