| 摘 要： | 对CDA常规直叶栅和4种端壁翼刀方案下叶栅内三维粘性流场进行了数值研究。分析表明,端壁不同位置上的翼刀不同程度上都阻断了近端壁区域压力面至吸力面的二次流动,翼刀上方偏向吸力面侧有反向"翼刀涡"产生,通道涡的强度被削弱;距压力面30%节距位置为安装端壁翼刀的最佳位置,可使损失降低7%～9%。计算结果和实验结果吻合较好。

| Abstract: | The numerical simulation has been carried out to investigate the effect of endwall fence on the secondary flow in a compressor cascade.The results show that the boundary layer fences can reduce the strong cross-flow from the pressure surface to the suction surface near the cascade endwall.A counter-rotating streamwise vortex is formed over the fence and the strength of the passage vortex is diminished.It is found that the fences are most effective when they are located 30 percent pitchwise from the pressure surface of the blade.For the optimum endwall fence location,the cascade loss can be reduced 7～9 percent compared with the conventional cascade. |
