WAVE ACTIONS ON A VERTICAL CYLINDER IN MULTI-DRIECTIONAL RANDOM WAVES

Yu-xiu Yu, Ning-Chuan Zhang, Qun Zhao

Abstract


The wave actions on a vertical cylinder in multi-directional random waves are experimentally studied in this paper. The two-dimensional (2-D) wave method is extended to calculate the three-dimensional (3-D) wave forces. The variation of various hydrodynamic coefficients with KC number and wave directional spreading are investigated. The three-dimensional wave forces are compared with that of two-dimensional waves.

Keywords
