Icing deteriorates the performance of wind turbine rotors by changing the blade airfoils’ shapes. It decreases the lift, increases the drag, and subsequently causes power production losses and load increase on turbines’ structures. In the present study, the effects of atmospheric icing on the performance of a controlled large-scale wind turbine is estimated through simulations. To achieve the target, the MS (Mustafa Sahin) Bladed Wind Turbine Simulation Model is used for the analyses of the National Renewable Energy Laboratory (NREL) 5 MW turbine with and without iced blades. Icing modeling is realized based on its main characteristics and its effects on blade aerodynamics. Turbine performance estimations are carried out at various wind speeds between cut-in and cut-out wind speeds in terms of various turbine parameters such as power, thrust force, blade pitch angle, and rotor speed. Simulation evaluations show that even a light ice accretion along the blades varies the turbine characteristics and dynamics, changes the cut-in and rated wind speeds, and affects the aforementioned turbine parameters differently in the below and above rated regions.

Effects of tip injection on the performance and near wake characteristics of a model wind turbine rotor
Abdulrahim, Anas; Anik, Ezgi; Ostovan, Yashar; Uzol, Oğuz (2016-04-01)
This paper presents an investigation of the effects of tip injection on the performance and near wake characteristics of a model wind turbine rotor. Experiments are conducted by placing a three-bladed horizontal axis wind turbine rotor at the exit of an open-jet wind tunnel. The rotor blades are non linearly twisted and tapered with NREL 5826 airfoil profile. The nacelle, hub and the blades are specifically designed to allow pressurized air to pass through and get injected from the blade tips while the roto...
Effect of steady and transient wind shear on the wake structure and performance of a horizontal axis wind turbine rotor
SEZER UZOL, NİLAY; Uzol, Oğuz (2013-01-01)
This paper presents an investigation of the effect of steady and transient free-stream wind shear on the wake structure and performance characteristics of a horizontal axis wind turbine rotor. A new three-dimensional unsteady vortex-panel method potential flow solver based on a free-vortex wake methodology, AeroSIM+, is used for this purpose. The code is validated using the experimental data from the National Renewable Energy Laboratory Unsteady Aerodynamics Experiments. The effects of vortex core model, co...
Effect of steady and transient wind shear on the wake structure and performance of a horizontal axis wind turbine rotor
Sezer Uzol, Nilay; Uzol, Oğuz (2009-12-01)
This paper presents an investigation of the effect of steady and transient freestream wind shear on the wake structure and performance characteristics of a horizontal axis wind turbine rotor. A new 3-D unsteady vortex-panel method potential flow solver based on a free-vortex-wake methodology, AeroSIM, is used for this purpose. The code is validated using the experimental data from the NREL UAE experiments, as well as checked against the theoretical models developed by previous researchers. Three-different i...
Effects of mie vanes and tip injection on the performance and wake characteristics of HAWT
Anik, Ezgi; Abdulrahim, Anas; Uzol, Oğuz (null; 2016-01-08)
This paper presents the results of an experimental study that focuses on the tip leakage/vortex control of a model horizontal axis wind turbine rotor. The effects of Mie vanes and tip injection on the performance and wake characteristics of a model horizontal axis wind turbine rotor are investigated through experiments that are conducted by placing a specially designed three-bladed horizontal axis wind turbine rotor at the exit of an open-jet wind tunnel facility. The rotor blades are non-linearly twisted a...
Effect of Fiber Orientation of Bend-Twist Coupled Blades on the Structural Performance of the Wind Turbine System
Şener, Özgün; Kayran, Altan (2017-01-05)
The effect of fibre angle of bend-twist coupled mixed GFRP-CFRP wind turbine blades on the structural performance of the wind turbine system is studied. For the structural performance evaluation, the effect of the use of off-axis plies in the main spar caps of the bendtwist coupled wind turbine blade on the reduction of damage correspondent internal loads in the whole wind turbine system, electrical power produced, tower-blade end gap, and maximum stress in the blades are taken as major criteria. Different ...
