Savonius wind turbine flow analysis with an open-source solver

Ovaj završni rad opisuje kako se vjetar, kao izvor energije, iskorištava, koje su mane i prednosti tog izvora, korištenje energije vjetra u raznim područjima te druge informacije o vjetru. Opisane su vrste vjetroturbina i bitne stavke kod aerodinamike vjetroturbina. Također je dan opis o računalnoj dinamici fluida, stavke pripreme analize u CFD-u te osnove o softverima koji se koriste u toj analizi unutar ovog rada. Sljedeće, modelirana je Savoniusova vjetroturbina u kojoj su postavljeni polumjera zakrivljenosti, omjera preklapanja i broja lopatica rotora i slično. Nakon toga generirana je mreža za stvorenu geometriju pomoću cfmesha koji je generiran te uređen u Pythonu. Postavljeni su rubni uvjeti i namješteni ostali parametri te je provedena analiza. Dobiveni rezultati uspoređeni su s ostalim istraživanjima.This final paper describes how wind, as a source of energy, is exploited, what are the disadvantages and advantages of this source, the use of wind energy in various areas and other information about wind. Types of wind turbines and important items in wind turbine aerodynamics are also described. It is also given a description of computer fluid dynamics, CFD analysis preparation items, and software basics used in that analysis within this paper. Next, a Savonius wind turbine was modeled in which the radii of curvature, the overlap ratio and the number of rotor blades, and the like were set. The grid for the created geometry was then generated using cfmesh which was edited by Python and generated. Boundary conditions and other parameters were set and analysis was performed. The obtained results were compared with other studies
