Flow-induced vibration as a sustainable and flexible source of energy

Fluid mechanics plays an important part in the mechanical systems. Its knowledge gives us the opportunity to extract energy from the fluid and doing it efficiently. So to be able to understand all the mechanisms around it allows to take the most of the energy available and thus knowing how to convert fluid energy in other forms of energy. In the branch of energy harvesting from flowing water, the most developed is the hydroelectric power generation using a turbine. Yet, harvesting energy from the water currents has naturally been investigated and in this circumstances, flow induced vibrations has emerged a promising source of energy extraction instead of just a source of noise problems and fatigue for the industry. The present study will show that this technology could be suited to the actual need of sustainable and flexible source of energy. Multiple experiments are carried out in that sense including the search for the optimal cross-section, the influence of the angle of attack and the effects of a control law.
