| Abstract: | The depth condition which represents the deep water cases in the calculation of the hydrodynamic coefficients is presented.Hydrodynamic coefficients for a floating vertical circular cylinder in water of infinite depth are obtained,and the unknown coefficients in the velocity potentials are solved by the method of matched eigenfunction expansions.The truncation terms needed is also discussed.It is shown that the hydrodynamic coefficients for a vertical circular cylinder floating in water of infinite depth ca... |
