1 1 SEE MSc. Thesis CFD simulation of flow field in a hydraulic turbine Meeting KTH SWECO TURAB

2 2 Overview of the Project Work Flow Project Timing

3 3 Project Approach 3 Main parts Structured meshing Using symmetry in mesh generation G.VB.RD.T

4 4 Meshing of Guide Vane Modified G.V geometry & opening angle

15 15 Meshing of Blade Runner

16 16 Meshing of Blade Runner

17 17 Meshing of Blade Runner Animation 1 Animation 2

18 18 Meshing of Draft Tube

19 19 Next Steps Exporting the meshes to the solver (Fluent) Taking a down to top approach (part to total) Each passage and part will be solved with inlet mass flow boundary condition seperatly ? Using pridiodicity for 3 G.V+4 B.R then apply the outlet as the inlet of D.T

20 20 Open questions Confirmation of the B.R spatial location relative to the rotor shaft CFX Turbo instead of the Fluent Turab factory+site visit
