HYDRODYNAMIC FORCES ON A FLOATING CYLINDER IN WAVES OF FINITE DEPTH.

Research output: Contribution to conferencePaper

Abstract

An indirect integral equation method is used in the paper to analyze the hydrodynamic forces, i. e. exciting forces, added mass and damping coefficients, of a two-dimensional floating cylinder in waves of finite depth. The series form of the Green's function, which has the advantage of avoiding the Cauchy principal value integral appearing in other forms, and the source-sink distribution technique are employed. It is found that the suitable terms for the series of Green's function and segment of the contour must be carefully selected in order to obtain more accurate results, especially for a rectangular shape body. The numerical results have been compared with those of other theories and good agreements are obtained. The technique developed in this paper is a rather simple and straightforward method which can be easier extended to a whole ship in oblique waves either with or without speed, or the case of a floating structure near quay etc.
