跨声速轴流压气机不同工况下转子激波与导流叶片尾迹相互干涉研究

摘要

应用3维黏性流动计算软件Fine/Numeca,对某型1.5级跨声速轴流压气机进行内部流场和全工况特性数值模拟,得到该压气机特性曲线。在最高效率点和近失速点,在2种质量流量下,对压气机内部流场进行非定常对比计算,分析了在质量流量变小时,压气机内部流场的变化情况。%The numerical simulation of internal flow and overall performance for a 1.5 stage transonic axial flow compressor was conducted by three dimensional viscous flow calculation software Fine/Numeca.The characteristic curves of the transonic axial flow compressor were obtained.The unsteady calculation of compressor internal flow was conducted at the maximum efficiency point and near stall point at two mass flow.The variations of the compressor internal flow were analyzed when the mass flow reduced.
