VIVACE stands for Vortex Induced Vibrations Aquatic Clean Energy, VIVACE technology is one of the best way to extract energy from flowing water currents and it is based on phenomenon of Vortex Induced Vibrations (VIV). Actually vortex is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow.
Lets see what VIVACE developer Michael Bernitsas, a professor at the University of Michigan department of naval architecture and marine engineering, said about VIVACE technology.
Though VIV are very destructive in nature and engineers are trying to prevent VIV from damaging offshore equipment and structures, there is a possibility of converting this VIV problem into valuable energy resource by Vivace technology. This Vivace technology works in flowing water moving slower than 2 knots or 2 mile per hour. Some of the great advantages of the VIVACE technology are:
- It uses robust design which are good for long run with a very small maintenance.
- Installations concerned with this VIVACE technology does not have any interference with other activities going on the water surface such as fishing, shipping.
- It is compatible with marine life.
- It has low dependence on ocean or river conditions.
