Modification of the Wake of a Cylinder: Effect of Small Amplitude Surface Perturbation (Technology #: 040506-01)
Alternate shedding of vortices from long slender structures may cause vortex induced vibration leading to fatigue type failure of the body by imposing periodic pressure changes on its surface. The invention of attenuation of regular formation of vortex shedding is achieved. The presence of a bi-stable instability has been discovered for cylinders...
