轴流压缩机叶轮流线曲率法反问题的研究

Research on the Inverse Problem of Streamline Curvature Method for Axial-flow Compressor Impeller

主要讨论了用流线曲率法构造轴流压缩机的气动反问题计算,首先通过平面叶栅法粗线条地得到一个轴流压缩机算例,然后着重介绍用流线曲率法求解压缩机叶片排间隙中S2流面反问题主方程,从而进一步优化叶型,并通过实例得出了设计计算结果。

It mainly introduces the reverse problem calculation for pneumatic axial-flow compressor using the streamline curvature method First, an axial-flow compressor example is roughly obtained using the method of plane cascade. Then the calculation of S2 stream surface reverse problem master equation in compressor blades clearance using streamline curvature method is especially introduced. Thus impeller profile is furthered optimized and the designing and calculating results are obtained by examples.
