NUMERIČKA ANALIZA STRUJANJA FLUIDA U DIFUZORU KAPLANOVE VODNE TURBINE

U završnom radu izrađena je numerička simulacija strujanja vode kroz difuzor Kaplanove vodne turbine. Geometrija difuzora napravljena je u programu Autodesk Inventor na temelju dostupnih nacrta. Nakon izrade geometrije uz pomoć programa Ansys izrađena je nestrukturirana numerička mreža. Numerička simulacija stacionarnog strujanja provedena je u programu Fluent za zadani protok. Prikazani su rezultati simulacije uključujući prikaze kontura tlakova, kontura i vektora brzina i strujnica.In this final thesis, a numerical simulation of water flow was created through the Kaplan water turbine. Based on the available schemes, the geometry of the diffuser was made in the Autodesk Inventor program. An unstructured numerical mesh was created after making the geometry with the Ansys program. Numerical simulation of stationary flow was conducted in the Fluent program for a given flow rate. The simulation results are presented, including representations of pressure contours, contours and vectors of velocities and currents
