CFD simulace vírové struktury v sací troubě Francisovy turbíny (Francis-99) při pod-optimálním provozu - srovnání s měřením / CFD simulation of vortex structure in the Francis turbine draft tube at part load operating point - comparison with measurements

This master's thesis deals with simulation of vortex structure which is created in the draft tube of Francis turbine, at part load flow conditions. The main objective is to get the most accurate results from the calculations, using the student license of Ansys Fluent 19.1. The results from the calculations are compared with the experiment under the Francis-99 project. Mainlly in terms of dynamic properties of vortex rope – aplitude and frequency of pressure pulsations. Additionaly the time-averaged velocity profiles are compared. I used the test-case provided by NTNU – Norwegian University of Science and Technology under the Francis-99 workshop series.
