| 摘 要： | 本文采用五孔束状测针和分布在叶栅上、下端壁及叶片表面的测压孔,对叶栅出口流场和上述表面上的静压分布进行了详细测量。实验结果证明:叶片的倾斜显著地改变了叶片表面尤其是吸力面上的静压分布,因而引起了叶栅中二次流损失的重新分布。

| Abstract: | In this paper,by using five-hole bunch shaped probes and through
the pressure measuring holes on the upper and lower end-walls of the
cascades and blade surfaces,the outlet flow field of the cascades and
the static pressure distributions on the above mentioned surfaces were
traversed,The experimental results prove that blade leaning has remark-
ably changed the static pressure distributions on blade surfaces,espe-
cially on the suction faces,leading to a redistribution of secondary
flow losses in the cascades. |
