Having demonstrated that the concept works in the laboratory, the Vortex Induced Vibration
for Aquatic Clean Energy (VIVACE) converter is currently being commercialised by University of Michigan spin-out Vortex Hydro Energy.
We call this hydrokinetic technology the Vortex Induced Vibration for Aquatic Clean Energy converter, or VIVACE for short.
Vortex induced vibrations of circular cylinders occur over a very large range of Reynolds numbers--between 40 and 150, between 400 and 300,000, and for Re greater than 500,000.
As well as detailed design, Feed, integrity management and engineering analysis services, it also specialises in complex subsea challenges such as vortex induced vibrations
, overtrawling and intelligent pigging.
a[euro]oeVivacea[euro] stands for Vortex Induced Vibrations
Aquatic Clean Energy.
First observed half a millennia ago by Leonardo DaVinci, "Vortex Induced Vibrations
" (VIV) could lead to clean, safe, renewable energy.
Expanded as Vortex Induced Vibrations for Aquatic Clean Energy, VIVACE doesn't depend on waves, tides, turbines or dams.
Vortex induced vibrations are undulations that a rounded or cylinder-shaped object makes in a flow of fluid, which can be air or water.
The major design challenge was fatigue damage due to a combination of vessel motion and vortex induced vibrations
. These were solved primarily using and developing design methods and cutting edge software.
