| 摘 要： | 详细测量了平行进口端壁附面层与设前导叶两种进口条件下某涡轮叶栅的出口流场。测量结果表明, 两种情况下在叶栅出口形成了类似的涡系结构, 但是条件不同涡系形成的机制不同。此外, 损失的大小与分布也发生了变化。

| Abstract: | The exit flow fields of a turbine cascade with or without the front guide vanes were investigated.The measured results show that the similar vortex structures are formed in these two cases,but the mechanisms of their formations are different.In addition,the amounts and distributions of the losses in the case with the front guide vane are also changed in comparison with those in the cascade without the front guide vanes. |
