A semi-cylinder placed in a water stream and attached to the beam is excited into vortex-induced vibrations (VIV), which triggers the piezoelectric deformation. pulsation and noise occur when the vortex shedding frequencies match, Pulsations and noise generated by flow through restrictions, Vibration of instrument connections inserted into the flow field, Pulsations and noise in shell-side heat exchanger cavities, Wind-induced vibration of tall towers & structures. 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). The inherent throttling action and complex 3D flow in control valves result in vibration and intolerable noise at small and medium valve openings.

Flow-induced vibration (FIV) occurs due to pressure pulsation in the flow that causes the pipe to vibrate. It covers the analysis of the vibrations of structures exposed to fluid flows; explores applications for offshore platforms and piping; wind-induced vibration of buildings, bridges, and towers; and acoustic and mechanical vibration of heat exchangers, power lines, and process ducting. First, with the use of high-strength materials, structures become more slender and more susceptible to vibration. For two cylinders, the converted power is 2.56-7.5 times the power of a single cylinder.
