... of horizontal fixed fins are attached between two hulls for the reduction of pitch motions, the fin effects were confirmed by the model tests. Running trims of the vessel are changed depending on the fins, so the seakeeping behaviors are analyzed with consideration of ship attitude. RMS values of pitch, roll...

... ABSTRACT In this paper, a circular cylinder attached by a pair of fin-shaped strips is proposed with intent to harvest hydrokinetic energy. It is found via numerical simulations of fluid-structure interaction that vortex-induced vibration and galloping occur back-to-back by placing the strips...

... ABSTRACT: The hydrodynamic force acting on a fin oscillating beneath a free surface is investigated. To safely utilize floating structures under severe environmental conditions in the sea, the motion of the floating body and the mooring forces acting on the body should be reduced. To decrease...

... motion is mainly arisen from inherent small damping, use of additional mechanism to provide roll damping can significantly reduce the roll motion. In this paper, a performance evaluation method of fin stabilizer, which is very useful for stabilizing roll motion of mid- and high-speed vessels...

... and pitching of a lunate shape wing. In this paper a trial to realize experimentally the high efficient propulsion by an artificial oscillating wing mechanism IS presented. 1. INTRODUCTION Many aquatic animals swim by the propulsion force generated from their fin movements. Especially, saurel, mackerel...
