Abstract: The following discussion reviews the research and development state of the art in pump-turbine hydraulics. Both experimental and numerical aspects are discussed. Indeed, more and more high-tech developments, [Parkinson, 1996], have to be used to fulfil the requirements of pump-turbines specifications, not forgetting the needs of deeper flow insight knowledge involved by the systematic introduction of Computational Fluid Dynamics (CFD) in design operations. The paper gives an overview on the current state of the art in the field of pump turbine hydraulic development. At the same time the limitations are also clearly identified. In order to tackle the problems, which are not resolved yet, research programs were launched including external resources from the Universities of Lyon, Lausanne but also from a team at Sulzer Innotec. Finally, one representative pump-turbine project in China, which recently has been put into operation, illustrates as an example the application of these long-term research and developments activities.
