An Integrated Flow Analysis System for the Recalculation of Hydraulic Machinery Bladings

The present paper deals with the recalculation of hydraulic machinery bladings. By combining numerical tools for the geometrical description of the bladings, mesh generation, different CFD flow models (Q3D Euler, 3D Euler, Navier-Stokes) and post-processing a highly efficient integrated flow analysis system is obtained. The capability of the developed software package is shown by recalculating water turbine runners of different specific speeds, a semi-axial and a radial centrifugal impeller. The results of the flow computations are compared to each other and to existing measurements.
