某型多级压气机三维流场分析

Analysis about Three Dimensional Flow Field in a Multistage Compressor

对某型压气机全三维流场进行了数值模拟,分析了该压气机的功、反动度、轴向速度等诸参数在每一级的分布特点,从总体参数上分析了多级地面压气机的设计特点;从型面压力分布、极限流线、以及能量损失系数等分析了地面压气机的叶型与叶片的设计特点。

Three dimensional flow field analyses about a multistage compressor was carried out in this paper. The power,reaction and axial velocity distribution in cascade along the spanwise were studied in details, the design characters was also studied. The blade geometry character was also analyzed by studying the pressure distribution along profile, limit streamline and loss coefficient distribution in cascade flow field.
