Local 3D numerical simulations are useful additions to a global assessment of hydropower plants. This paper presents an overview and three sample cases, which were conducted as part of a recent modernization project involving an existing high-head power plant operated by the TIWAG (Tiroler Wasserkraft AG). ANSYS-CFX software was used to evaluate the connection between the headrace power tunnel and the new surge tank, including the penstock and the asymmetric orifice in the surge tank. For the third example, FLOW-3D software was used to assess an upper chamber of the surge tank. © 2013 Springer-Verlag Wien.
