摘要
在Adkins-Smith二次流模型的基础上 ,建立了轴流压缩机端部损失模型 ;通过对轴流压缩机稳定性影响因素的分析 ,提出了时滞参数状态修正的概念 ;将端部损失与时滞参数的状态修正相结合 ,建立了考虑叶尖间隙对压缩系统稳定性影响因素的计算系统。计算结果表明 :叶尖间隙对压缩系统稳定性有着重要的影响。
On the basis of the end-wall model loss, the end-wall loss in tip region is calculated by quasi-3D Through-Flow Method. According to the analysis about the axial compression system stability, the dynamic modification on the time-lag parameter has been presented by incorporating the end-wall loss into the axial compression stability model. The calculating system concerning the effects of tip clearance on axial compression stability has been established. The calculated results show that tip clearance has strong effects on the axial compression system stability.
