槽式处理机匣几何结构参数的正交试验

Orthogonal experimental investigation of geometry structure of grooved casing treatment

针对一亚声速单级轴流压气机试验台,根据正交试验的要求设计了9种周向槽机匣处理结构.以其为载体系统地研究了槽式机匣几何结构参数对其扩稳效果的影响.正交实验结果表明:在两种换算转速下无需对所用可能组合的处理机匣结构进行试验,使用正交分析方法对试验结果进行分析都能成功预测扩稳效果最好的处理机匣结构型式.

Nine kinds of circumferential grooved casing treatment structures were designed by the orthogonal experiment s requirement.Optimized experiments of the geometry structure of circumferential groove were performed on a single stage subsonic axial compressor with the nine kinds of circumferential grooved casing treatment structures at two rotor speeds.The results of orthogonal experiments show that the orthogonal experiments are successful.It is not necessary to test all casing treatment of possible combinatio...
