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). Tighten the clearances in-between pipes and supports. These flow-related phenomena are called Flow-Induced Vibration. The VIVACE concept and its application, Oscylator-4, enhance fluid-structure interactions and, by controlling the response, harness power. Unlike viscous damping, squeeze-film damping and friction damage are poorly understood and difficult, Flow induced vibrations cause by instability is the subject of this investigation. Unfortunately, in many situations, the problems occur after the components are already in operation; the "fix" usually is very costly. <> It can be found in products such as fertilizers, cleaners, and Hi There!
