Full Article:

Nowadays, looking to reduce global warming and improve sustainability energy, wind turbine generators are a real alternative for clean power generation. To withstand wind forces, aerogenerators should be analyzed properly to ensure a good operation in the system lifetime. Several approaches can be established to perform analysis and design of this kind of structures. In this paper, an engineering solution considering fluid structure interaction is presented. Wind action is modelled thru a stabilized fluid flow formulation, while the structure (wind turbine) is solved with geometrically nonlinear shell elements with only translation degrees of freedom. In both cases, the finite element method is used to found a solution. Interaction between both formulations are capable to reproduce spin of turbine blades, including self weight forces and time history analysis to obtain stresses and acting forces for several operational conditions.
