Prediction of S-shaped characteristics in reversible pump-turbines using different numerical approaches

Autor: Markus Lenarcic, M. Giese, A. Jung, Ch. Bauer

Publikováno v: IOP Conference Series: Earth and Environmental Science. 49:042009

The prediction of characteristics and flow phenomena in reversible pump-turbines becomes increasingly important, since operations under off-design conditions are required to respond to frequency fluctuations within the electrical grid as fast as poss

Numerical investigation of a high head Francis turbine under steady operating conditions using foam-extend

Autor: Markus Eichhorn, Christian Bauer, Markus Lenarcic, Stefan Schoder

Publikováno v: Journal of Physics: Conference Series. 579:012008

In this work the incompressible turbulent flow in a high head Francis turbine under steady operating conditions is investigated using the open source CFD software package FOAM-extend- 3.1. By varying computational domains (cyclic model, full model),
