在本文件中，详细的实验研究。研究了叶片载荷对环形压气机静叶栅二次流结构发展和相互作用的影响。在四种不同的叶片载荷下获得了3%弦轮毂间隙的实验结果。包括叶片和端壁流动可视化、端壁静压的时间分辨测量、通道内的径向-周向热线横向测量以及通道入口和出口处的五孔探针横向测量。实验获得的结果给出了详细的洞察力的影响的发病率的发展和相互作用的间隙涡，马蹄涡，通道涡。此外，它将表明，涡破裂的间隙涡发生在较高的负载。
Within the present paper, a detailed experimental investigation is presented. The influence of blade loading on the development and interaction of secondary flow structures within an annular compressor stator cascade (CSC) is examined. Experimental results at 3% chord hub clearance were obtained at four different blade loadings. Included are blade and endwall flow visualization, time resolved measurements of the static pressure on the endwall and radial–circumferential hot-wire traverse measurements within the passage as well as five-hole probe traverse measurements at the inlet and the outlet of the passage. The experimentally obtained results give detailed insight on the effect of the incidence on the development and interaction of the clearance vortex, horseshoe vortex, and the passage vortex. Furthermore, it will be shown that a vortex breakdown of the clearance vortex occurs at higher loadings.
