We have developed an efficient and robust CFD method to compute a strongly nonlinear interaction between wave and ship,such as heave and pitch motions in a severe wave condition, resultant slamming on the surface of a ship and an impact pressure due to green-water phenomena. The proposed method is based on coupling the Eulerian method for fluid phase with the Lagrangian method for solid phase to compute fluid-structure interaction. In this model, two kinds of Lagrangian particles are employed. One is free surface particle located near the free surface to capture a water surface accurately. The other one is SPH particle to compute ship motions in 3D. A fully nonlinear phenomenon with wave breaking is treated on a fixed Eulerian grid with the free surface particles to rebuild density function for capturing an interface between two phases in a filamentary under resolved region. In this study, the proposed model was applied to ship-wave interaction for evaluating of seakeeping of a ship in waves and their results were compared with experimental results and strip theory.
