Résumé

Different coupling mechanisms between a flow and a structure are presented in this chapter. They are derived in the context of structural linear dynamics by identifying fluid-induced added masses, dampings or stiffnesses. These dynamical effects may induce different energy transfers between the fluid and the solid that can lead to different instabilities. The objective of this chapter is firstly to classify the different instability mechanisms, secondly to show how some of these mechanisms are triggered by the addition of a classical viscous damping, and finally to use them to convert the kinetic energy of a flow into electricity through a simple example.
