STUDY OF LOW-REACTION BOUNDARY LAYER SUCTION AXIAL COMPRESSOR AND IT'S INTERNAL FLOW CONTROL

本文进一步分析了低反动度附面层抽吸式压气机概念,并讨论了该压气机的设计要点和应用范围;分析了抽吸掉的附面层内的低能高熵流体的可能利用途径,以及对于不同的利用方式,效率的评估方法;基于上述概念设计了一台亚声速低反动度附面层抽吸式压气机,详细地分析了该压气机的气动参数选取与分布特点,以及该压气机内部的三维分离流动及其控制规律。

In this paper, further analysis of low-reaction boundary layer suction axial compressor design concept was carried out. The design elements and application area of this concept were also discussed. The possible utilization ways of the low energy and high entropy fluid that was aspirated were studied and the evaluation method of each way was given out. Based on the design concept, a subsonic low-reaction boundary layer suction axial compressor was designed. The selection rules of aerodynamic parameters and the 3D separation flow control method were detailedly studied in this paper.
