| 摘 要： | 本文实验研究了采用直、弯静叶的某重复级低速压气机在不同时序位置时的总性能及横截面流场特性.在不同流量工况下对压气机整体性能及流场进行了详细测量.结果表明,采用正弯静叶的压气机时序效应相对较弱且喘振裕度有所增加;同时,在压比略有减小的前提下(0.1%级别),凭借消耗扭轴功的大幅F降(3%左右),效率在设计工况下最大可提高...

| Abstract: | Experimental investigation was done in a double stages low speed axial compressor with both straight and bowed stators.Overall performance and traverse flow field were measured in different work condition.The results show that the clocking effect weakens and the stall margin increases while the bowed stator is used.Although the total pressure ratio decreases about 0.1%, the efficiency raises about 1%with the reason of torque input decreasing(about 3%).At the design condition,there are two vortexes exist in ... |
