Experimental and Numerical Analysis or Free Surface Flows in a Rotating Bucket

The aim of this study was to provide a complete experimental and numerical analysis of the flow in a rotating Pelton bucket. For the experimental analysis, several functioning points have been used in order to study differences which may occur in various situations. This analysis will be mainly provided by the pressure distribution in the bucket and will be supported by flow visualisations. Thanks to these results, five distinct zones within the bucket have been isolated each corresponding to different signal characteristics. The numerical simulation has been performed using the two-phase homogeneous method in an original way by considering the relative path of the jet and the relative velocity changing with the rotation of the wheel. These simulations were performed for the same experimental functioning points.
