摘要通过数值模拟，分析了叶片周向弯曲对大折转角压气机叶栅内分离结构的影响。 - A numerical investigation about effects of boundary layer suction in low - speed compressor stator cascade with large turning angle was carried out
摘要本文采用数值方法研究了低速条件下附面层抽吸对大折转角矩形叶栅流场的影响。 - Experimental studies on the influences of the deflected plates upon the oscillations were focused on the attenuations of sound pressures of the oscillations with the bent plates of various angles and lengths . the results show that the bent plates with angels of 30 ~ 60 and a length about an oscillating wavelength diminish the sound pressures notably . with the same angle of 45 , the half - wavelength bent plates diminish the pressures , and the one - wavelength or longer bent plates do better
结果表明，当折转角为30 60和折转长度( b )与振荡波长( )相当时( b / 1 . 0 ) ，折板具有显著的削弱振荡声压的效果；折转角45时，折板长度与振荡基频波长之比b /在0 . 5 ，折板就有削弱振荡声压的效果， b /在1 . 0或更大时削弱效果更佳。 - In this dissertation , a hybrid optimization approach for automatic design of 3d turbine blades was proposed and well implemented . the applications to the stacking design optimization and full 3d aerodynamic design optimization for an annular cascade demonstrated the validity , robustness and efficiency of this hybrid approach
