This project, conducted within the framework of the Chaire EOLE with educational input from Siemens Gamesa, explores the dynamic interaction between wind turbulence and wind turbine structures, particularly focusing on the fore-aft bending due to aerodynamic forces. This research examines how wind turbulence affects turbine stability and longevity, using computational simulations and theoretical models to measure and predict these impacts. Through this collaboration, the project benefits from cutting-edge industry insights and tools, enhancing its practical relevance for future wind energy systems.<\/p>\n\n\n\n

Key Findings<\/h3>\n\n\n\n
    \n
  1. Turbulent Wind Modeling<\/strong>: The Mann model was used to simulate isotropic turbulence, creating a realistic turbulent wind field. Adjustments were made to match a turbulence intensity of 10%, providing a controlled environment to analyze turbine responses.<\/li>\n\n\n\n
  2. Thrust Force and Structural Response<\/strong>: Simulations showed the thrust force acting on turbine structures due to turbulent wind. Calculations indicated significant variations in force depending on rotor size and hub height, affecting turbine movement and bending moments.<\/li>\n\n\n\n
  3. Fore-Aft Displacement Analysis<\/strong>: By solving the displacement response equation, the study demonstrated that displacement varied by rotor size, with smaller rotors showing larger amplitude variations in response to the same turbulent conditions.<\/li>\n\n\n\n
  4. Frequency and Bending Moments<\/strong>: The Power Spectral Density analysis revealed dominant frequency responses that align with theoretical predictions. The analysis also highlighted bending moments at the turbine base, crucial for understanding load dynamics under turbulent forces.<\/li>\n\n\n\n
  5. Design Implications<\/strong>: Findings emphasize the importance of turbulence-resilient designs. By quantifying the structural loads from turbulence, the study provides insights for optimizing turbine resilience, ensuring both efficiency and safety in wind energy systems.<\/li>\n<\/ol>\n\n\n\n
