| Outline of Final Research Achievements |
Ship maneuverability under heavy weather is one of important themes for safety. In order to understand the detail of ship motion, it is necessay to carry out large scale gas-liquid-solid multiphase simulations. We have developed a CFD code based on LBM (Lattice Boltzmann Method) with a two-phase free-surface model. The proposed two-phase model is based on a free-surface model, and both liquid and gas phases are independently time-integrated. It was confirmed that proposed method can evaluate impact pressure by splash and basic air behavior. Finally, we achieved a fluid-structure interaction simulation by using a full-scale ship data, and the effectiveness of our method was also confirmed.
