| 摘 要： | 实验研究了低速条件下局部附面层吸除对高负荷扩压叶栅气动性能的影响.采用五孔气动探针测量了叶栅出口截面气动参数,并对叶片表面静压进行了测量,详细分析了局部吸气方式、吸气量和吸气位置对叶栅出口截面总压损失和负荷能力的影响.结果表明,采用吸力面两端吸气和中间吸气方式均能够有效吸除叶栅流道内低能流体,增加叶栅的气动负荷,从而提高叶栅的气动性能;采用吸力面两端吸气对叶栅气动性能的改善要优于吸力面中间吸气;叶栅气动性能的改善主要在靠近叶展中部区域,而对角区核心区和端部区域的影响并不明显.

| Abstract: | The detailed experimental investigations into the effects of local boundary layer suction on aerodynamic performance of highly-loaded compressor cascade were carried out in low-speed condition. The exit aerodynamic parameters were measured by five-hole aerodynamic probe, and the distribution of the profile static pressure on the blade surface was obtained. The effects of local suction type, suction location and suction flow rate on the exit total pressure losses and load capacity of cascades were analyzed in detail. The results show that the effective low-energy fluid removal through the side suction and middle suction on suction surface can increase the cascade load capacity, effectively improve the cascade aerodynamic performance. The influence of the side suction on suction effectiveness is better than that of the middle suction. The cascade aerodynamic performance has an obvious improvement in the region of middle blade, but the chance of the cascade aerodynamic performance is not clear near the end wall region. |
