Outline of Final Research Achievements

The purpose of this study is to propose the simulation method of a small ship’s motions in wash wave. Authors have proposed a reproduction method of wash wave by multi-segmented wave generators which are controlled by using computed results of CFD. Moreover, wash wave and ship motions in wash wave were simulated by 3D-NWT (three dimensional numerical wave tank). 3D-NWT can simulate wash wave in the same manner as the multi-segmented wave generators in ASMB. Input data of both methods are the computed wash wave by CFD. Simulated wash wave and ship motions in wash waves by 3D-NWT is in good agreement with the measured results in ASMB. These simulated results indicate that 3D-NWT is able to simulate wash wave reproduced by wave generator and ship motions in wash wave.
