摘要

通过实验和数值模拟的手段研究了尾迹与边界层的相互作用

其中上游叶排尾迹的模拟是通过在涡轮叶栅前设置周期性运动的圆柱实现的.研究表明

上游尾迹对涡轮叶栅边界层的发展有显著影响

在其作用下

吸力面边界层提前转捩

分离得到明显的抑制

利用尾迹与边界层相互作用的非定常效应可以明显提高低压涡轮叶栅气动负荷.

Abstract

The wake-boundary layer interaction had been investigated numerically and experimentally

and a periodicity moving bar wake had been used to imitate the upstream wake.The study shows that the wake has a significant influence on the boundary layer of cascade: the transition on suction surface has taken place in advance;the separation has been remarkably suppressed;the load of low-pressure turbine cascade has been increased obviously.
