中文摘要：
提出一个基于二维流动基础上的线性化旋转失速稳定性模型,该模型可以通过求解特征值来预测低速轴流压气机的失速边界.叶片几何对流动的影响用一个体积力模型来代替.给出了有限差分法和谱配置法两种离散特征方程的方式,并且在针对一台低速压气机和一台跨声压气机转子在低转速的情况进行了算例的验证,结果表明该模型能够比较准确的预测低速压气机失速边界.
英文摘要：
A two-dimensional linear stability model was presented,which can be used to estimate the inception point of rotating stall in axial flow compressors by solving the eigenvalues,the effects of the blade rows in compressors on the flow field have been modeled by body force source terms in the momentum equations.Two methods,finite difference and spectral collocation methods,have been used to discretize the eigenvalue equations.The validations of model have been performed in two different cases,and the results s...
