Icing on wind turbine blade under various atmospheric conditions

It is important to predict the ice shape with amount of accreted mass on the surface of turbine blade in order to design and develop de/anti-icing systems for wind turbines located in cold climate regions. Ice accretion on the blades change the initial shape and this cause alteration in the aerodynamic characteristic of the blades. To this end, icing module combined with the BEM method to predict the shape of the iced blade sections of the turbine blade under atmospheric icing conditions. The obtained results are verified with experimental and numerical ice shapes reported in the literature. In all the cases studied, the current numerical tool yields results that are in fair agreement with the compared results and can be used to predict ice accretion on wind turbine’s blades under atmospheric icing conditions.

Ice accretion prediction on wind turbine blades and aerodynamic shape optimization for minimizing power production losses
Yırtıcı, Özcan; Tuncer, İsmail Hakkı; Özgen, Serkan; Department of Aerospace Engineering (2018)
The global wind energy resources are plentiful in cold climate regions and mountainous areas, which cause ice formation on wind turbine blades. Prediction of ice accretion on wind turbine blades makes it possible to estimate the power losses due to icing. Ice accretion on wind turbine blades is responsible for significant increases in aerodynamic drag and decreases in aerodynamic lift, and may even cause premature flow separation. All these events create power losses and the amount of power loss depends on ...

This study is presented here that the stress characteristics of an existing 5-meter composite wind turbine blade for 30 kW wind turbine designed for METUWIND is known by using finite element method. Modal and static analysis is performed in order to obtain static and dynamic behavior of the blade. To perform analysis, the geometric three-dimensional model of the blade is obtained by using two-dimensional drawings of the blade. After geometric modeling of the blade, the materials that are used in blade struc...
Load Reduction in Wind Turbines with Bend-Twist CoupledBlades without Power Loss at Underrated Wind Speeds
Atalay, Oğuz; Kayran, Altan (null; 2018-01-01)
Usage of composite materials in wind turbine blades is a passive mechanism to alleviate fatigue loads besides the reduction in the mass of the wind turbine system. Off-axis plies in bend-twist coupled (BTC) blades account for the passive fatigue load reduction by reducing the effective angle of attack of blade sections. Reduction in fatigue loads is generally represented by damage equivalent load ratios. In the present study, multibody aeroelastic analyses are performed for wind turbine systems for the unde...

YIRTICI, ÖZCAN; Tuncer, İsmail Hakkı; Özgen, Serkan (2016-10-07)
Ice accretion on wind turbine blades modifies the sectional profiles and causes alteration in the aerodynamic characteristic of the blades. The objective of this study is to determine performance losses on wind turbines due to the formation of ice in cold climate regions and mountainous areas where wind energy resources are found. In this study, the Blade Element Momentum method is employed together with an ice accretion prediction tool in order to estimate the ice build-up on wind turbine blades and the en...

İçen, Mustafa.; Çöker, Demirkan; Department of Aerospace Engineering (2019)
In this thesis, a test setup for the experimental 5 meter RÜZGEM wind turbine blade and that can be used for small scale wind turbine blades up to 9 meter is designed and analyzed. The purpose of this thesis is to help establishing the test infrastructure under METUWIND project such as NREL, RISØ, CRES. The literature on the existing facilities is reviewed. After that, RÜZGEM wind turbine blade is introduced and design loads are presented. To apply these loads appropriately to the blade, the moment distribu...
