| 摘 要： | 应用轴流压缩系统的逐级动态响应模型对平面波型压力扰动下的多级压气机瞬态响应及气动稳定性进行了较详细的数值分析。对－ ８级跨声压气机的数值模拟结果表明， 基于流动阻塞机理建立的压缩系统稳定性判别准则是合理和可靠的。结果还进一步建立进口扰动频率与压气机瞬态响应间的关联关系

| Abstract: | An application of stage by stage dynamic model to transient response of axial compressors to inlet planar wave pressure disturbance was presented.The detail numerical analyses for a eight stage transonic compressor were given.The results show that new criterion for predicting aerodynamic stability base on the airflow blockage and dynamic airflow time variation is practicable and reliable.The quantitive relationships between the inlet pressure oscillation frequency and transient response or the critical stage are also established. |
