摘要

采用数值方法对两级低速压气机中径处的流场进行非定常模拟。研究第二排静叶在两个典型周向位置上的叶片气动负荷

分析各列叶栅气动负荷的非定常波动以及静叶时序效应对叶栅气动负荷的影响。对各列叶栅的非定常气动力和气动力矩进行频谱分析

探讨叶列间的非定常气动干扰。结果表明

时序效应对静叶片气动负荷的影响明显高于动叶片的。时序效应能够提高压气机的性能与叶片寿命.

Abstract

Numerical simulation was applied to the unsteady flow at the mid span of a twostage low-speed compressor.The aerodynamic load of the second row of stator blade at two typical circumferential positions was investigated.The influence of unsteady aerodynamic load of each blade cascade and the stator clocking effect on blade aerodynamic load was also analyzed.Through spectrum analysis of the unsteady aerodynamic forces and moments of each blade cascade

the unsteady aerodynamic interferences between blades were discussed.The results show that

the influence of stator clocking effects on the stator blade's unsteady aerodynamic loads is larger than that on the rotor blade.Stator clocking effect can help improve the compressor performance and its blade service life.
