通过吹风实验,探讨了在不同径高比和外壁面扩张角的汽轮机环形静叶栅中叶片倾斜对叶栅出口流场的影响.实验结果表明:采用最佳倾斜角叶片能降低叶栅能量损失和改善叶栅出口流场的气动性能.图9参10
The influence of blade inclination on the flow field at the exit of the cascade in the ring turbine cascade with different aspect ratio and outer wall expansion angle was discussed by the air blowing experiment.The experimental results show that the energy loss of the cascade can be reduced by using the optimal inclination angle blade And to improve the aerodynamic performance of the flow field at the exit of the cascade
