OpenFOAM SIMULATION OF THE FLOW IN THE HöLLEFORSEN DRAFT TUBE MODEL
Paper i proceeding, 2005

This paper presents OpenFOAM computational results of the flow in the Hölleforsen hydraulic turbine draft tube model. It is a contribution to the third Turbine-99 workshop on draft tube flow (www.turbine-99.org). The boundary conditions and the wall-function grid of 'Case 1: Steady calculation' is used. Turbulence is modelled using the standard k-epsilon model with wall functions. The results are analysed at sections where detailed measurements are available. Detailed comparisons between the results presented in this paper, computational contributions from other participants, and measurements are available in the workshop proceedings (see www.turbine-99.org).
