Abstract
In order to investigate fundamental characteristics of three-dimensional corner separations of decelerating cascade flow, a channel flow around a NACA65 blade in a decelerating flow by turning was examined. Five-hole probe survey showed that the exit flow of the blade had a few similar points to the cascade flow in that the accumulation of the low-energy fluid on the corner part, the secondary flow and the pitchwise periodicity of the wake. PIV measurement showed that the focus-type separation was seen in the momentary streamline along the suction surface of the blade, whereas no apparent separation was seen in the flow along the endwalls.
