水波と浮体の強非線形相互作用に関する数値計算法と実験的検証

抄録

At Research Institute for Applied Mechanics (RIAM) of Kyushu University, a Cartesian-grid method in combination with CIP-based interface capturing schemes is being developed for computing extremely nonlinear wave-body interactions. To confirm validity of this calculation method, careful and systematic experiments of both two- and three-dimensions are also carried out. In this paper, following a brief description of the calculation method, some recently obtained numerical results are shown for violent water-wave behavior around the ship's deck and resultant impulsive pressure and ship motions, which are compared with corresponding experiments.
