The present paper describes the parametric design of a Francis turbine runner. The runner geometry is parameterized by means of a 3D inverse design method, while CFD analyses were performed to assess the hydrodymanic and suction performance of different design configurations that were investigated.
This paper describes a new design method of blade geometry for a Francis turbine runner by using a threedimensional inverse design method and the Computational Fluid Dynamics (CFD) technique.
