The Analysis of Viscous Wakes Noise in Axial Flow Compressor

本文研究了微弯机翼在正弦阵风作用下的脉动升力,并导出计算公式,分析了动、静叶栅几何及气动参数对转子脉动升力及噪声级的影响。

This paper studies the fluctuating lift of a cambered airfoil under sinusoidal gusts. The calculating equations of the fluctuating lift are then derived. The effects of cascade geometry parameters and aerodynamic parameters of rotor cascade and stator cascade in axial flow compressor to the rotor fluctuating lift and noise level are analyzed.
