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.
