This combination of higher power and smaller volume resulted in an order of magnitude increase in power-to-volume density. Indeed, microcylinders with diameter equal to the 5% of the chord have a negligible impact into the flow field and are not effective, at least at the Reynolds number of the present simulations. Vortex induced vibrations make use of the flow energy and convert this power of the fluid to oscillate the cylinder. The classification enables engineers to identify all possible sources of excitation in a given system and to assess potential dangers. Flow-induced Vibration i.e, the fluid flow generates high kinetic energy that forces the piping system to vibrate ( Piping Vibration is induced in the system by Fluid flow). to up to 50 people.
