Modern design of pump-turbines
2009 IEEE Electrical Power & Energy Conference (EPEC), 2009The increasing interests in the market and the challenging hydraulic requirements call for new developments in the field of pump-turbines. For the Tongbai project ANDRITZ HYDRO has developed a new pump-turbine, applying the modern numerical tools of flow simulation for optimization of all components.

Computational Study of Pump Turbine: Partial Load Operations
Volume 3: Computational Fluid Dynamics; Micro and Nano Fluid Dynamics, 2020Abstract The performance of a pump-turbine under partial flow rates, 85%, 75%, and 65%, is studied using the LES model. The power signal, velocity, vorticity, and pressure field is presented over the blades and throughout the draft tube. Pressure fluctuations are probed at various locations over the wall of the draft tube.

For the purpose of optimizing pump turbines installed in pumped storage plants with regard to efficiency, cavitation, and excavation costs, a method of computation has been devised which includes a new system of determining type number and impeller outside diameter. An example employing data applicable to a modern pump turbine—Rodund 2(Austria)—reveals
