Resumen:
Analysis results, obtained from
numerical simulation, for non-linear and unsteady aeroelastic behavior of large
horizontal-axis wind turbines are presented in this paper. Simulations are
carried out using a partitioned scheme of weak interaction that allows dealing with
the fluid-structure interaction problem by using one method to solve the
structural dynamic problem and another method for the aerodynamic problem. The
aerodynamic model used is the non-linear, unsteady vortex lattice method (NLUVLM).
The structural model used is a system of beam finite elements and rigid bodies with
finite rotation. This provides a very general tool with relatively low
computational cost. The proposed method allows predicting from the operating
conditions (wind speed and direction, pitch angle of blades, etc.) the
aeroelastic response of wind turbines, characterized by variables such as
rotation speed of the rotor, loads on the structural components and the
extracted power, among others.
