摘要

利用KochCC提出的"有效静压升系数法"估算了宽广雷诺数范围内的多级轴流压气机的不稳定边界。不同雷诺数条件下的计算结果表明

随雷诺数的降低

压气机的稳定性下降

下降的幅度取决于雷诺数及其本身的设计。本文采用的方法可以分析宽广雷诺数范围内各级和整台压气机的增压能力及稳定性

从而对高空低雷诺数下的压气机设计提供指导性的帮助。

Abstract

In this paper

the stability of a multi-stage compressor in an extensive range of Reynolds number is estimated by using the method of estimating the maximum pressure rise potential.The results prove that the stability of compressors deteriorates with the decline of Reynolds number.The method used in this paper can analyse the pressure-rise potential and stability of each stage and the whole compressor as well in an extensive range of Reynolds number.It is envisaged to provide helpful information on the designing of the axial compressors working at low Reynolds number.
