Small wind energy harvesting converts aeroelastic vibration into electricity and can provide independent power supplies for low-power-consumption sensors, which are not convenient replacing chemical batteries frequently. As harvesters collect sustainable from the ambient environment, they environmentally friendly saving. The most widely adopted wind-induced mechanisms designing vortex-induced (...

The effect of Reynolds number on curves the transverse-only motion amplitude a circular cylinder with body mass m∗=0.935 and damping ratio ζ=0.00502 in turbulent flow range is investigated systematically using two-dimensional in-house code developed based lattice Boltzmann method. Large eddy simulation chosen as turbulence model to describe viscous, incompressible Newtonian fluid immersed bound...

We present results from two-dimensional numerical simulations based on Immersed Boundary Method (IBM) of a cylinder in uniform fluid flow attached to bistable springs undergoing Vortex-Induced Vibrations (VIV). The elastic spring potential for the springs, consisting two wells, is completely defined by spacing between minima and depth wells. perform VIV with linear spring, as well different int...
