不同密流比压气机叶型优化设计与流动分析OA

AVDR has significant impact on the aerodynamic performance of compressor blade,and in order to study the influence law of AVDR on compressor blade designan automatic optimization method was used to optimize the stator blade design with different AVDR,and the flow characteristics and blade surface load distribution at zero Angle of attack were analyzed.The results show that with the increase of the dense flow ratio,the load near the leading edge of the stator optimal blade gradually decreases,while the load in the middle and rear section gradually increases,the peak Mach number and its position basically remain unchanged,the range of available attack Angle gradually increases,and the minimum loss does not change significantly.The load near the leading edge of the optimal rotor blade gradually increases,while the load in the middle and back section basically remains nunchanged.The peak Mach number increases,the peak Mach number is close to the front edge,the range of available attack Angle gradually increases,and the minimum loss decreases.
