| 摘 要： | This paper presents a detailed experimental investigation concerning the influence of blade loading (incidence)on the three-dimensional flow in an annular compressor cascade.The data are acquired at four incidence anglesunder low Mach number and low Reynolds number conditions.Experimental techniquss include the oil-filmvisualization on the profile and the endwall surfaces,the laser-sheet visualization of the flow field inside theblade passage,and the measurement by radial-circumferential traveress using a seven-hole probe.The behaviorand nature of the three-dimensional flow with severe separations inside the blade passage and at the exit areobtained.The distributions of the total pressure loss,static pressure,velocity and outflow angle are also given.These results are valuable for establishing the physical model of the three-dimensional complex flow in axialcompressors and for examining the computational procedures.
