Abstract: This paper presents the simulation of the dynamic behavior of variable speed pump–turbine. A power reduction scenario at constant wicket gate opening was numerically analyzed from 100% to 93% rpm corresponding to a power ...

Abstract: The most common mechanical equipment adopted in the new generation of pumpedhydro power plants is represented by reversible pumpturbines (RPT), required to rapidly switch between pumping and generating modes in order to ...

Abstract: This study employs an incompressible homogeneous flow framework with a transport-equation-based cavitation model and shear stress transport turbulence model to successfully reproduce the unsteady cavitating flow around a ...
