为探索利用端壁造型技术来提高轴流压气机性能的可能性,以亚声轴流压气机试验级为对象,对端壁造型技术在压气机中的应用进行了研究.鉴于压气机的逆压工作环境,端壁设计结合了周向(非轴对称)和流向两个方向的造型,具体介绍了造型方法.对端壁造型后压气机级的数值模拟显示:端壁造型技术可以有效减小、消除静子角区分离,进而提高级的效率和压比. In order to explore the possibility of improving the performance of axial-flow compressor by using end-wall molding technology, the application of end-wall molding technology in compressor was studied for subsonic axial flow compressor test stage. Pressure working environment, the end wall design combined with the circumferential (non-axisymmetric) and flow direction of the two shapes, specifically describes the modeling method.After the end wall modeling compressor stage numerical simulation shows that the end wall modeling technology can effectively reduce Small, eliminate the static corner separation, and thus improve the level of efficiency and pressure ratio.
