摘要
详细测量了平行进口端壁附面层与设置导向叶栅两种进口条件下后加载涡轮叶栅的气动参数。测量结果表明, 导向叶栅的设置加强了实验叶栅内的横向流动,这就造成了“C”型压力分布(弯叶片)和具有正径向压力梯度的压力分布(直叶片)产生的位置较无导叶时提前了。
The aerodynamic parameters of the aft-loaded cascades with or without the guide vanes were investigated. The measured results show that the cross flow in tested cascades became stronger when setting the guide vane, so the positions of the 'C' type pressure distribution (bowed cascade) and the positive radial pressure gradient (straight cascade) formed earlier than that not set the guide vane.
