Power Control Optimization of an Underwater Piezoelectric Energy Harvester [PDF]
, 2018 Over the past few years, it has been established that vibration energy harvesters with intentionally designed components can be used for frequency bandwidth enhancement under excitation for sufficiently high vibration amplitudes.

Vortex-Induced Vibration Suppression of a Circular Cylinder with Vortex Generators
Shock and Vibration, 2016 The vortex-induced vibration is one of the most important factors to make the engineering failure in wind engineering. This paper focuses on the suppression method of vortex-induced vibration that occurs on a circular cylinder fitted with vortex ...

Vortex Nucleation Induced Phonon Radiation from a Moving Electron Bubble in Superfluid 4He
, 2010 We construct an efficient zero-temperature semi-local density functional to dynamically simulate an electron bubble passing through superfluid 4He under various pressures and electric fields up to nanosecond timescale. Our simulated drift velocity can be

The Physics of FluidsTower-like structures with circular section are prone to unexpected across-wind vortex-induced vibration (VIV), and the along-wind response is usually neglected due to its amplitude being much smaller than that of VIV.

A numerical study of an inline oscillating cylinder in a free stream [PDF]
, 2011 Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

Empirical decomposition method for modeless component and its application to VIV analysis
International Journal of Naval Architecture and Ocean Engineering, 2015 Aiming at accurately distinguishing modeless component and natural vibration mode terms from data series of nonlinear and non-stationary processes, such as Vortex-Induced Vibration (VIV), a new empirical mode decomposition method has been developed in ...

Drag Coefficients of a Long Flexible Circular Cylinder with Wake Interference [PDF]
, 2009 Drag coefficients of the downstream cylinder in a tandem arrangement of two models aligned with the flow are shown in this work. The models, which experienced vortex-induced vibrations with wake interference, had an external diameter of 16 mm and a ...
