机匣处理是一种扩大压气机稳定工作范围的新技术。其扩稳的机理目前还不太清楚.本文改进与修正了G.R.Ludwig等人在文献[1]中的分析法,引伸于带多孔壁机匣处理的实际压气机转子叶排中,对各种多孔壁机匣处理的扩稳机理作出了统一的分析.并对其失速起始点和失速裕度的改进量给出了定量的估算.经实验证明,理论分析是可 Casing processing is a new technology that expands the compressor’s stable operating range. The mechanism of its stabilization is still not clear at present.This paper improves and modifies the analysis method of GRLudwig et al [1], and extends the actual compressor rotor blade row with porous wall casing treatment, Porous casing treatment stability expansion mechanism made a unified analysis of its stall starting point and stall margin improvement given a quantitative estimate of the experimental results show that the theoretical analysis can be
