propagation stall
rotating stall
Examples
- Experimental study of small perturbation induced rotating stall in axial flow compressor
轴流压气机小扰动诱发旋转失速的试验研究 - Experimental study shows : it was able to distinguish between rotating stall and the inlet vortex . ,
实验表明，旋转失速和进口涡流能够区分，且区域界限分离明显。 - So under some situations , for example at the point of inception of surge or rotating stall , wet compression can be used to vanish surge and rotating stall , which will extend compressor steady operation region
在一定的条件下，如在系统刚发生喘振或旋转失速的时候，喷水湿压缩可以用来消除喘振或旋转失速，这有利于增大压气机的稳定运行范围。 - Abstract : concerning the models for discribing aerodynamic stability of axial flow compressor , the original model is one - dimensional , and it is reasonable for the onset of surge only . for the onset of rotating stall , there are just some two - dimensional models at published literatures . a three - dimensional aerodynamic of compressor has been presented in this paper . an aerodynamic stability model concerning radial disturbance of compressor is presented . the calculated results show that the occurrence of radial disturbance is related to the axial velocity disturbance , which has important effect on aerodynamic stability of compressor . the position of onset of stall , in blade tip or hub , is dependent upon the characteristics of blade element . the comparisons of calculated results predicted by 2d and 3d aerodynamic stability model have also been made in this paper
文摘:轴流压气机的气动稳定性模型，最初为一维模型，仅适用于描述喘振发作.对于旋转失速发作，在公开文献中有一些二维模型发表.本文提出了一类考虑压气机径向扰动对失速影响的新的气动稳定性模型.计算结果表明压气机的轴向扰动往往随着径向扰动的产生，径向扰动的强度影响压气机的气动稳定性，在叶尖还是叶根首先产生失速与压气机基元叶栅特性密切相关.本文对轴流压气机二维和三维气动稳定性模型的计算结果进行了对比分析 - Simulation results show that the surge line moved up - left relative to the original one and surge margin became larger when wet compression is used , which means wet compression can extend steady - operation regions of compressors and the si a - 02 gas turbine . at last , based on the moore - greitzer model surge and rotating stall of a compression system with wet compression is modeled with consideration of inlet evaporative cooling and compressor pressure rise when wet compression is used
哈尔滨工程大学博士学位论文最后，本文在压缩系统moors grei上zer模型的基础上，考虑进口蒸发冷却的作用和压气机湿压缩过程的作用，推导出了湿压缩系统喘振和旋转失速的统一模型，该模型可以模拟系统发生喘振和旋转失速时的瞬态响应以及喷水湿压缩对系统瞬态响应的影响。
