A Complete procedure for predicting and improving the performance of HAWT's
Al-Abadi, A.; Ertunç, Özgür; Sittig, F.; Delgado, A. (IOP Publishing, 2014)A complete procedure for predicting and improving the performance of the horizontal axis wind turbine (HAWT) has been developed. The first process is predicting the power extracted by the turbine and the derived rotor ... -
A design and optimization method for matching the torque of the wind turbines
Al-Abadi, A.; Ertunç, Özgür; Weber, H.; Delgado, A. (AIP Publishing, 2015)An aerodynamic shape optimization method for a horizontal axis wind turbine is developed and verified through experimentation with a laboratory-scale wind turbine. Our method is based on matching the rotor's and the coupled ... -
From passive to active pitch regulation of wind turbines: Optimization method with numerical validation
Al-Abadi, A.; Kim, Y.; Park, J.-Y.; Kang, H.; Ertunç, Özgür; Delgado, A. (ASME, 2015)An optimization method that changes the control strategy of the Horizontal Axis Wind Turbine (HAWT) from passive- to active-pitch has been developed. The method aims to keep the rated power constant by adjusting the blade ... -
Interaction between free-stream turbulence and tip-vortices of wind turbine blades with and without winglets
Al-Abadi, A.; Kim, Y.; Ertunç, Özgür; Epple, P.; Delgado, A. (IOP Publishing, 2018)Experimental investigations of the free-stream turbulence impact on the tip-vortices generated in wind turbine blades have been performed. The investigation is done by exposing an efficient laboratory scale wind turbine ... -
A torque matched aerodynamic performance analysis method for the horizontal axis wind turbines
Al-Abadi, A.; Ertunç, Özgür; Weber, H.; Delgado, A. (Wiley, 2013-11)An analysis method is developed to test the operational performance of a horizontal axis wind turbines. The rotor is constrained to the torque–speed characteristic of the coupled generator. Therefore, the operational ... -
Turbulence impact on wind turbines: experimental investigations on a wind turbine model
Al-Abadi, A.; Kim, Y. J.; Ertunç, Özgür; Delgado, A. (IOP Publishing, 2016)Experimental investigations have been conducted by exposing an efficient wind turbine model to different turbulence levels in a wind tunnel. Nearly isotropic turbulence is generated by using two static squared grids: fine ...
