High-damping, high-Reynolds VIV tests for energy harnessing using the VIVACE converter
J.H. Lee,Michael M. Bernitsas +1 more
TL;DR: In this paper, the VIVACE converter enhances VIV to harness horizontal hydrokinetic energy of water flows, and high Reynolds and high-damping are required to operate VIVAC in ocean/river currents.

Flow induced motion and energy harvesting of bluff bodies with different cross sections
TL;DR: In this paper, the authors investigated the flow induced motion and energy conversion of cylinders with different cross sections using two-dimensional unsteady Reynolds-Averaged Navier-Stokes simulations in the Reynolds number range of 10,000 Â 30,000.
Journal ArticleDOI
A review of bluff body wakes
TL;DR: In this article, the authors reviewed the wakes of different cross-sectional bluff bodies, including circular, square, triangular and rectangular cylinders, and the dependence on the two parameters of Strouhal number, vorticity, circulation, and efflux angle of vortices in the wake of bluff bodies.

Numerical simulation and experimental validation for energy harvesting of single-cylinder VIVACE converter with passive turbulence control
TL;DR: In this article, passive Turbulence Control (PTC) in the form of roughness strips is applied to enhance FIM and increase the efficiency of the VIVACE converter in harnessing marine hydrokinetic energy.

2-D URANS vs. experiments of flow induced motions of two circular cylinders in tandem with passive turbulence control for 30,000<Re<105,000
TL;DR: In this article, the flow induced motions (FIM) of two rigid circular cylinders, on end linear-springs, in tandem are studied using two-dimensional Unsteady Reynolds-Averaged Navier-Stokes (2-D URANS) simulations verified by experimental data.
