In order to investigate fundamental characteristics of three-dimensional separations of decelerating cascade flow, a channel flow around a NACA65 blade in a decelerating flow by turning was examined. Effect of attack angles of 31deg. and 35deg. on the channel flow was focused on. Five-hole probe survey showed that the location of accumulation of the low-energy fluid was at 0.2 and 0.75 of the height ratio for 31deg. whereas around midspan for 35deg. PIV measurement showed that various focus-type separations were seen in the flow for 35deg., and the three-dimensional vortex structure was considered by using a vortex filament.
