Résumé

In this article, we investigate the movement and vibrations of a blade due to the presence of the mast. When the blade goes past the mast, a sudden pressure spike induces vibrations in the blade. To study the influence of the stiffness, two different structures have been investigated. We present our numerical methodology concerning solving the flow, the structure behavior and the coupling of the two systems. Then, we validate two methods against an experiment (Bahaj et al., 2007). In a third section, we present fluid-structure interaction cases. Several structures are setup by modifying the stiffness of the material. Their steady open-water (without a mast) behaviors are compared. And finally, two dynamic fluid-structure are performed to compare the behavior of an elastic blade passing next to a mast. For all the cases, we use K-FSI developed by K-Epsilon to solve the fluid-structure interaction (FSI) effects.
