| 摘 要： | 本文提出了一个基于直接数值计算结果基础上的旋转失速线性稳定性模型,描述了如何从基本的Navier－Stokes方程出发，把轴流压气机流动稳定性问题转化为一个特征值问题的基本理论框架。对压气机不稳定边界的判断通过计算和检验特征值的方式来实现。本文给出了有限差分法和基于Gauss－Lobatto节点的谱配置方法两种数值离散的方式，并分析了这两种离散方式的收敛特性。

| Abstract: | A linear stability model of rotating stall based on numerical computation results has been established, which described a general approach to set up a eigenvalue problems, and stall margin of axial compressors can be judged by estimating the eigenvalues. Two different methods,finite difference method and spectral collocation method,are proposed to discretize the equations and their convergency are compared. |

| Keywords: | axial compressor rotating stall stability eigenvalue finite difference method spectral method |
