多扇平行压气机模型在压气机稳态畸变流场计算中的应用

MULTIPLE-SECTOR PARALLEL COMPRESSOR MODEL FOR FLOW FIELD CALCULATION UNDER DISTORTION

描述了一个轴流压气机在进口稳态畸变条件下流场计算的方法。借助多扇平行压气机模型，采用流线曲率法，求解完全径向平衡方程，计算压气机内各叶排进出口气流参数的分布，从而得出压气机在进口畸变条件下流场的详细情况。以一台单级压气机为例，进行了进口总压、总温和气流角周向畸变条件下的流场计算，证明其结果是合理的。

This paper describes in some detail the method for computing an axial-flow compressor flow field under distortion.Based on the multiple-sector parallel compressor model and stream line curvature method,the stage distributions of the parametres of distorted flow field,such as total pressure,total temperature,static pressure,static temperature,air velocity and swirl angle,are obtained by solving the radial-equilibrium equation,then the details of compressor flow field under the given inlet distortion can be reached.As an example the flow field computation for a single stage compressor has been completed under the inlet circumferential distortion.The results demonstrate the practical value of the method.
