Oba rotorja sta bila modelirana v SolidWorksu in simulirana v Ansys CFX. Na podlagi izračunanih obratovalnih karakteristik Cp(λ) so bile primerjane učinkovitosti. Rezultati kažejo, da aerodinamični rotor doseže skoraj petkrat višji izkoristek. Vizualizacija tlaka in hitrosti dodatno potrdi večjo učinkovitost aerodinamične zasnove. CFD izračun omogoča poglobljen vpogled v tokovne razmere in potrjuje pomembnost aerodinamično oblikovane geometrije lopatic. This bachelor's thesis presents a comparative analysis of two wind turbine rotors; one with an aerodynamic blade profile and one with a simple rectangular profile. Both rotors were modeled in SolidWorks and simulated in Ansys CFX. Based on the calculated Cp(λ) operational characteristics, their efficiencies were compared. The results show that the aerodynamic rotor achieves almost five times higher efficiency. Visualization of pressure and velocity further confirms the superiority of the aerodynamic design. The CFD computation provides detailed insight into the flow field and confirms the importance of aerodynamic blade geometry. mehanika tekočin računalniška dinamika tekočin vetrna turbina oblikovanje rotorja primerjava obratovalnih karakteristik fluid mechanics computational fluid dynamics wind turbine rotor design comparison of operational characteristics true true false [K.
