通过数值模拟,采用融合多种流动控制手段的三维气动布局设计方法,设计了一对单级高负荷轴流压气机进行对比研究。研究结果表明:从传统压气机设计角度出发,采用复杂的三维气动布局设计方法,设计所得的压气机性能仍具备较大的提升空间。而将压气机内的设计矛盾重新分配,以最大程度地利用流动控制技术,可以显著提升压气机在设计点的气动性能,并明显拓宽压气机的稳定工作范围。
By numerical simulation, adopting complex 3D aerodynamic layout integrating a variety of flow control technologies, a pair of single-stage highly loaded axial compressors have been designed for comparative research. The results show that, proceeding from traditional compressor design ideas, even adopting complex 3D aerodynamic layout, the performance of compressor still has a large space for improvement. While reassigning the compressor design contradictions, to take best advantages of flow control technologies, the aerodynamic performance at designed point of compressor can be improved significantly, and the stable operating range can be broadened substantially.
