Master Thesis An Experimental Investigation of the Parameters To Classify Wind Sites(Izmir Institute of Technology, 2002) Türkeli, Hayri Murat; Özerdem, BarışWind data measured on Izmir Institute of Technology campus area have been used to evaluate the wind power potential on this location. Measured data set and its evaluation showed that Izmir Institute of Technology campus area has a considerable wind potential. Mean wind speeds have been found 7.03 m/s at 10 m height and 8.14 m/s at 30 m height. The prevailing wind direction has also been found as north direction. WAsP and WindPRO softwares have been used to evaluate the wind statistics and energy calculations. Wind turbines with 600 kW and 1500 kW nominal power have been fitted as the most efficient ones. Suitable sites were selected according to created average wind speed map and wind energy maps of campus area.Fourty seven 600 kW turbines with a total capacity of 28.2 MW and twenty six 1500kW turbines with a total capacity of 39 MW were located on the selected sites separately. The annual energy productions of the 600 kW and 1500 kW wind turbines have been calculated as respectively 100.3 GWh/year and 122.4 GWh/year.Master Thesis Comouter-Aided Aerodynamic Design of Small Scale Horizontal Axis Wind Turbine Blades(Izmir Institute of Technology, 2012) Göçmen, Tuhfe; Özerdem, Barış; Özerdem, Mehmet BarışIn this thesis, aerodynamic design of 1, 5, 10, 25, 50, 100, 250 and 500 kW horizontal axis wind turbine generators has been performed. The design procedure starts with the design and analysis of airfoils done by programs of PROFOIL and XFOIL, respectively through which the structural, aerodynamic and aeroacoustic principles have been taken into consideration. Then, the performance parameters of designed profiles were inputted to the constructed modified blade element momentum theory (BEM) code together with the main design parameters in order to obtain 3D blade geometry. The code is validated using MIE wind turbine with a rated power of 8 kW. The generated blade geometries are then analyzed using commercial computational fluid dynamics CFD code Numeca FINEâ„¢/Turbo and the velocity and pressure distributions around the blade have been visualized, separately. Moreover, the power coefficient, Cp was calculated and the power curves of the designed wind turbine rotors were drawn.
