摘要
试验性的调查为斜流动扇子的定子的内部流动被进行。中心表面和定子片的吸表面附近的角落分离上被集中。以设计流动率，在定子插头减少的轴的速度和全部的压力的价值接近吸表面在在由角落墙的影响的中心表面附近。以设计流动率的 80 90 % 的低流动率，表面能被发现的在吸表面和中心之间的角落分离，它广泛地变得在设计流动率的 80 % 传播了。
Experimental investigations were conducted for the internal flow of the stator of the diagonal flow fan. Comer separation near the hub surface and the suction surface of the stator blade are focused on. At the design flow rate, the values of the axial velocity and the total pressure at stator outlet decrease near the suction surface at around the hub surface by the influence of the comer wall. At low flow rate of 80-90 % of the design flow rate, the comer separation between the suction surface and the hub surface can be found, which become widely spread at 80 % of the design flow rate.
