NUMERICAL ANALYSIS OF THE FLOW AROUND A ROTOR OF WINDTURBINE DLR DEBRA 25

U okviru diplomskog rada napravljen je projekt vjetroturbine s naglaskom na aerodinamiku rotora. Odabran je klasični tip vjetroturbine uzgonskog tipa s horizontalnom osi rotacije i 3 lopatice. Željena snaga vjetroagregata iznosi 100 kW. S obzirom da je cilj izlazna snaga vjetroturbine od 100 kW, u skladu s time izvršen je aerodinamski proračun lopatice. Na lopatici je provedena numerička simulacija strujanja u svrhu provjere karakterističnih aerodinamskih parametara, tlaka i brzina.In the framework of the this thesis, a wind turbine project was developed, focusing on the aerodynamics of the rotor. The classic type of wind turbine with a horizontal axis of rotation and 3 blades was chosen. The power ouput of the wind turbine is 100 kW. Given that the target is the power output of the wind turbine of 100 kW, accordingly the aerodynamic calculation of the blades was performed. A numerical flow simulation was performed on the blades for the purpose of checking the characteristic aerodynamic parameters, pressure and velocity. situations
