This paper provides a brief overview of progress in our understanding of flow-induced vibration in power and process plant components. STATE OF THE ART: VIVACE has established the following:High power density with up to 4 cylinders in close proximity.Efficiency reaching 88% of Betz limit.Adaptive damping increasing power 51%-95% in single-cylinder and 50% in two-cylinder synergistic FIO.Applicable understanding of synergistic hydrodynamics FIO.Simple geometry and durable structure.Real 3-D converter as opposed to point, line, or area converters. What is Acoustic-Induced Vibration or AIV? Synergy between multiple cylinders results in efficiency of over 80% of the Betz limit. 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. PRODUCTS DEVELOPED Lab testing with up to four cylinders in tandem. These added supports will minimize the shaking tendency of the pipe, thus reducing the tendency of pipe failure. hUmO0+qT*@$`$xm4qPE&z}W?O#x@h 2B0ICcrie(\$JmiilnM.

In many cases, Lighthill's theory can, nevertheless, be applied successfully, and it is the most commonly-used model for the study of flow-induced sound and vibration. Calculations showed that LCOE strongly depends on flow velocity and the target of $0.15/kWh can be achieved with improvements to the Oscylator-4 and at higher flow speeds. View PDF; Download full issue; Energy. The study can also include FIV excitation of small-bore piping and components in the flow, such as thermowells. lazyLoad: true, The Converter can operate in low flow speeds, which represent the vast majority of flows in rivers, tides, and ocean currents. Despite their variety, the vibration phenomena from many different engineering fields can be classified into a relatively few basic excitation mechanisms. Flow-induced vibration, or vortex shedding, is due to high flow velocities such as in a piping dead leg of a centrifugal compressor system. Second, the development of advanced nuclear power reactors requires high-velocity fluid flowing through components, which can cause detrimental vibrations.
