   Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

4. 3. STRUCTURAL ANALYSIS OF TRUSS CONSTRUCTION FOR WIND TURBINE BLADES

   University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

   Author : Björn Weddig; [2016]
   Keywords : Wind turbine blade; FRP; Truss system; Instability; Buckling; Non-Linear; Eigenvalue problem; Frequency response analysis; Transient dynamic response; Technology and Engineering;

   Abstract : The usage of wind turbines during the latest years has grown substantially and are becoming an increasingly important source of renewable energy, as many countries are trying to reduce their reliance on fossil fuels. In order to increase the effect of the wind turbines the length of the blades has been increased, which has also led to an increase of the cross-section dimensions. READ MORE

5. 4. A stochastic analysis of Turbulence Intensity influence over various sizes of HAWT : Study of hypothetical relationship between Rotor Diameter and influence level of Turbulence Intensity

   University essay from Högskolan i Halmstad/Energivetenskap

   Author : Allen Christo Nicholas; [2016]
   Keywords : Turbulence intensity; power performance; power deviation; power coefficient; tip speed ratio.; Turbulensintensitet; effektuttag; effektavvikelse; verkningsgrad; löptal;

   Abstract : This disquisition aims for the study of turbulence intensity influence over the power performance of different sizes of turbines with the intent to validate a hypothesis. The hypothesis formulated for the analysis is the relationship between the rotor diameter (turbine size) and turbulence intensity. READ MORE

6. 5. Feasibility Study of a 3D CFD Solution for FSI Investigations on NREL 5MW Wind Turbine Blade

   University essay from KTH/Kraft- och värmeteknologi

   Author : Giacomo Bernardi; [2015]
   Keywords : HAWT; CFD; Aeroelasticity;

   Abstract : With the increase in length of wind turbine blades flutter is becoming a potential design constrain, hence the interest in computational tools for fluid-structure interaction studies. The general approach to this problem makes use of simplified aerodynamic computational tools. READ MORE
