POWER GENERATION USING NON-LINEAR VORTEX-EXCITED VIBRATION OF A HORIZONTAL CIRCULAR CYLINDER IN UNIDIRECTIONAL FLOW

Abstract

 The characteristics of power generation using non-linear vortex-excited vibration of a circular cylinder in steady open channel flow were estimated with considering the variation of a) the amplification of hydrodynamic forces acting on the vortex-excited vibrating cylinder in comparison with the hydrodynamic forces acting on the test cylinder stationary mounted and b) the amplitudes of transverse vibration of the test cylinder were evaluated quantitatively. The maximum values of power generation using vortex-excited vibration of the test cylinder were appeared in the range of 2< K_sa <4.
