Post stall transient model for axial compressor with closed-coupled valve under non-constant speed condition

  • 摘要: 为了给各种压气机喘振主动控制器提供验证平台,提出了一个新的旋转失速及喘振模型.该模型在Moore-Greitzer轴流压气机过失速瞬态模型的基础上,考虑了转子动态及旋转失速高阶谐波对压气机气动稳定性的影响,并且在模型中增加了紧连阀作为执行机构.仿真结果表明:随着压气机转速的增加,压气机的失稳行为由旋转失速转为喘振;压气机转速的变化作为系统内部扰动,可能使压气机在节流阀开度较大时便进入气动失稳状态;虽然压气机初始扰动仅含有1阶谐波,但随着旋转失速的发展,高阶谐波强度不断增长而变得不可忽略.
