The resent paper proposes a three-dimensional boundary element method based on velocity potential for a swept turbine cascade spanning parallel walls in which the flow turning angle is very large. The local aerofoil characteristics over the span-surface pressure distributions, circulation, aerodynamic force-and furthermore, the local flow characteristics in the outlet-trailing vortex strength, outlet velocity, turning angle are clarified in close relation to swept angle and aspect ratio. In particular, the three-dimensional flow behaviour in the vicinity of up and downstream end of the span are examined. Lastly, the present method is confirmed to be appropriate by comparisons with Gothardt-Stark's experimental results. The cosine rule is also clearly demonstrated to hold true for the swept turbine cascade.
