Two-dimensional calculations show that the NACA65 cascade flow that has 45 deg. of turning, 1.24 of solidity and 17 deg. of stagger angle is equivalent to the channel flow that has 14 deg. of stagger angle in terms of pitchwise blade force. Experimental investigation by five-hole probe shows that the accumulations of low energy fluid can be seen around the corner part and the overturning flow due to the secondary flow exists. And, as the periodicity of the blade wake in a pitchwise direction is comparably good, the wake of this channel flow is similar to the wake of the cascade flow for two pitch portion. PIV measurement results shows that a vortex pattern can be seen in the momentary streamline on the suction surface of the blade and in the averaged streamline on the perpendicular to both the suction surface and the endwall.
