On the Distribution of Aerodynamic Load and Stress on Wind Turbine Blade

Making use of a large database obtained from high-fidelity CFD simulations of a 5MW NREL wind turbine, we perform an analysis of loading distributions on different sections of the turbine blade and their possible shifts with respect to the change in the operating conditions, i.e. inflow wind speed, rotating speed, tilt and pitch angles. In this paper, we will present a computational fluid dynamics model designed for mass generation of aerodynamic loading data, a finite element analysis structural model for simulating the turbine deformation and stress. Finally, verification of the model, data processing and analysis, and the results of loading and stress distributions on different sections of the turbine blade will be presented.
