This preview shows page 1 - 3 out of 4 pages. Models are developed for both multi-degree-of-freedom aerodynamic galloping and vortex induced oscillation of bluff structures. shedding frequencies approach the structural natural frequencies, the, fluid-structure interaction becomes strongly coupled and dangerous. The strength of the unsteady pressure fluctuation is widely used to measure the hydro-induced vibration performance, but it consumes too much time to perform an unsteady numerical simulation compared with a steady one.

High-frequency piping vibrations are called acoustic-induced vibration (AIV), because the flow is mostly gas and the vibrations typically produce sound waves within the range of human hearing. Third model relaxes an assumption about the form of vibration in spatial direction and uses the vorticity formulation of equation of fluid motion to account for fluid-solid interaction.

It is particularly geared toward assessing the possible sources of excitation in a flow system, in identifying the actual danger spots, and in finding appropriate remedial measures or cures. The necessary conditions of flow-induced vibration for a carbon steel specimen attached to a larger styrofoam cylinder were first investigated. It is more prevalent near turbulent sources such as pipe bends, reducers, branch connections (Tee connections), partially closed valves, process equipment connections, etc. 83 0 obj <>stream Benefits to the public: An environmentally compatible technology can be developed to harness MHK energy even from slow current/river/ocean flows. 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). Oscylator-4 can be redesigned for self-deployment to nearly eliminate the cost of deployment/retrieval and reduce CAPEX dramatically.
