3 Applications in Energy Harvesting

In recent years, the use of flow-induced vibrations to harvest kinetic energy from environnemental flows has been the focus of a incrediblely large amount of scientific papers. Although the engineering interest and applicability in terms of economic or durability are still open questions, the concepts have raised numerous of interesting fundamental questions that are still open: what efficiency can we theoretically expect from these designs? How to optimize this efficiency? For a particular design or at a particular scale is piezoelectricity or induction the more efficient electromechanical coupling?

In this section, the basic modelling of flow-induced vibrations coupled to energy harvesting circuits is presented. Linear stability is addressed as well as non linear saturation of the instabilities.
