20.500.12556/RUL-171366 Analiza in primerjava karakteristik klasičnega in toroidalnega propelerja Analysis and comparison of classic and toroidal propeller characteristics V magistrski nalogi smo izvedli primerjavo in analizo klasične in toroidalne vetrnice za aplikacijo vetrne turbine. Najprej smo izpopolnili merilno mesto iz diplomske naloge z izboljšanjem togosti konstrukcije. Nato smo izvedli eksperimentalne meritve sile, hitrosti zraka, hrupa in števila obratov ter iz teh podatkov izračunali navor, kotno hitrost in moč oziroma koeficient moči. Vzporedno smo v programskem okolju Ansys izvedli analizo CFD za oba modela pri enakih robnih pogojih. Dokazali smo, da toroidalna vetrnica proizvede večjo moč pri enakih pogojih oziroma ima večji izkoristek. Pri nizkih vrtljajih generira manj hrupa kot klasična vetrnica. Na koncu smo z analizo tokovnic hitrosti pokazali, da je velikost vrtinčenja na konicah toroidalne vetrnice manj intenzivna kot pri klasični. In the master thesis, we compared and analyzed classic and toroidal wind turbines for wind turbine applications. First, we improved the measuring station from the bachelor thesis by improving the rigidity of the structure. Then, we did some experimental measurements of force, air speed, noise, and number of revolutions, and used this data to calculate torque, angular velocity, and power or power coefficient. In parallel, we performed a CFD analysis for both models under the same boundary conditions in the Ansys software environment. We demonstrated that the toroidal wind turbine produces more power under the same conditions and has greater efficiency. At low speeds, it generates less noise than a conventional wind turbine. Finally, we used velocity streamline analysis to show that the size of the vortex at the tips of the toroidal wind turbine is less intense than that of a conventional wind turbine. aerodinamika vetrna turbina vetrnica analiza CFD vetrovnik koeficient moči aerodynamics wind turbine windmill CFD analysis wind tunnels power coefficient true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-08-23 08:32:25 2025-08-23 08:32:27 2025-08-31 03:40:04 0000-00-00 00:00:00 2025 0 0 XX, 58 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.548.4:533.6.075:519.6(043.2) 274661 246960643 42957.pdf 42957.pdf 1 08ED5372AA0FE9DACEA6AD8D96C5BD25 874d610d4d16c4594ac0ab32a64c2762982bd36c68fa2702c6553cda52f733a0 d28c7520-7fea-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214653 Fakulteta za strojništvo 0 0 0
