Abstract: A technique is proposed for generating a set of surfaces of a toroidal draft tube of a hydraulic turbine, depending on 19 geometric parameters and constructing grids in its region to find the optimal shape based on numerical simulation of flows.

Keywords: hydraulic turbine, draft tube, surface modeling, finite element grid. .
