| 摘 要： | 在原Moore-Greitzer模型的基础上，发展了一个描述轴流压缩系统动态失速过程的一阶非线性模型。该模型耦合了旋转失速和喘振，并考虑了旋转扰动波中高阶谐波分量的影响，可用于详细分析旋转失速/喘振的动态特性、由失速状态退出的恢复特性，及系统参数的影响等。 |
| 关 键 词： | 压缩系统 旋转失速 喘振 恢复特性 |

| Abstract: | Based on the theory developed by Moore and Greitzer, a new simplifying approximation, which takes into account the influence of higher harmonics of rotating waves, is proposed to get a simplified model of post stall transients in axial compression systems. This model consists of a set of three simultaneous nonlinear first order partial differential equations.It is shown that the further investigations of post stall behavior for different response modes of instabilities (rotating stall and/or surge), recoverability from rotating stall or surge, and the effect of compression system parameters on them can be carried out by this model. |
| Keywords: | compression system rotating stall surge recoverability |
