Abstract

Performance of open type cross-flow runner utilizing waterfall is strongly affected by flow impinging position. It is therefore necessary to keep the stable generation by changing the runner position or controlling the waterfall direction. The former is unrealistic method because of sophisticated mechanism to move the runner. Accordingly, this study focused on the flow direction control method by using curved channel. Flow visualization and runner performance measurement were conducted about two different curvature channels. As a result, it was clarified that the flow direction control method was effective to keep a stable generation when the flow rate changed widely. Namely, the adjustment of runner position is not necessary even when the flow rate changes. This is an extreme advantage from a practical application viewpoint.
