Vortex Induced Vibration Aquatic Clean Energy

Mechanical Engineering

VIVACE stands for Vortex Induced Vibration Aquatic Clean Energy. It is a unique hydrokinetic system that relies on ‘Vortex Induced Vibration’ and on conventional energy forms like waves, tides, turbines or dams. The equipment used to harness this energy is called ‘VIVACE’. It works in flows moving slower than 2 knots (about 2 miles per hour). Most of the Earth’s current are slower than 3 knots. Turbines and water mills need an average of 5 or 6 knots to operate efficiently. VIVACE uses physical phenomenon of vortex induced vibration in which water current flows around cylinders including transverse motion. The energy contained in the movement of the cylinder is then converted to electrical energy using suitable rack and pinion mechanism.
