摘要
根据 Greitzer集中参数模型 ,导出了应用于离心压缩系统的喘振模型。利用该集中参数模型对 K.E.Hansen等进行实验所采用的离心压缩系统进行数值模拟 ,数值计算结果表明 ,该集中参数模型能较好地描述小型离心压缩系统的深度喘振振荡。
By analyzing Greitzer's lumped parameter model for surge of an axial compressive system, a lumped parameter model for surge of a centrifugal compressive system was deduced in this thesis. It was applied to numerical simulating the transient responses of a centrifugal compressive system subsequent to a perturbation from steady operating conditions, and the centrifugal compressive system was which K.E.Hansen had carried out experiments on. The calculated results indicate that the model can describe the surge of the small scale centrifugal compressive system perfectly.
