摘要
为了解决高负荷超声速压气机内部的复杂流动问题,利用抽吸槽对超声速压气机二维叶型进行附面层抽吸。本文采用数值模拟方法,验证了抽吸槽开取的必要性,并针对抽吸背压、抽吸槽位置以及抽吸槽宽度对二维叶型中流动控制的影响进行了计算分析,得到抽吸槽开取的最佳方案,有效解决超声速压气机二维叶型中激波和附面层分离的流动干扰问题,为超声速压气机的准三维设计提供参考。
In order to Solve the complex flow problems in highly loaded supersonic compressor, boundarylayer suction was carried out by using suction slots in two - dimensional supersonic compressor blades.This paper verifies the necessity of opening a suction slot by the numerical simulation method. Then theeffect of suction pressure, suction slot location and suction slot width on flow control in two - dimensionalcascade was calculated and analyzed, and the optimal way of opening a suction slot was found. It effec-tively solves the interaction problems between shock waves and boundary layer separations in the super-sonic two - dimensional compressor blades. Accordingly, it provides references for quasi - three dimen-sional design of supersonic compressor.
