Outline of Final Research Achievements

Standing waves generate along the streamwise direction on the surface of water flow through the convex channel. It was revealed that each waves have regularity in the spanwise direction of the channel, and its amplitude strongly depends on the water velocity and the curvature of the channel. The flow pattern is also occurred on the water guide for a waterfall type hydraulic turbine. In case of the turbine, the wave degrades the turbine performance due to shift from the optimum water impinging position to the runner. The setting angle of the straight part which is connected tangentially to the curved channel was investigated. As a result, higher performance is obtained for lower angle. The performance improvement effect is much remarkable for larger flow rate condition.
