Abstract

At Research Institute for Applied Mechanics (RIAM) of Kyushu University, extremely nonlinear wave-body interactions have been studied by means of CFD techniques and the computer code developed in partial cooperation with ClassNK, named RIAM-CMEN (computational method for extremely nonlinear hydrodynamics), is validated in several ways. In this paper, the frequency response characteristics of the wave-induced motions and added resistance on a ship running at constant forward speed in waves are compared to various results measured in a newly conducted experiment and computed by NSM (new strip method), EUT (enhanced unified theory), RSM (Rankine source method), and RIAM-CMEN. It is shown that the overall agreement of computed results by RIAM-CMEN is relatively good as compared to other linear-theory results.
