dc.description.abstract | In this study, wave drift forces and moments acting on an advancing ship in bow waves are investigated using an in-house numerical code that can solve highly nonlinear wave-body interaction problems. The program is called wave and viscous flow analysis system for hull form development (WAVIS) that has been developed by Korea Research Institute of Ships and Ocean engineering (KRISO). Basically, the finite volume method with block-structured mesh and non-staggered allocation is used to discretize unsteady RANS equations. The SIMPLEC method is adapted for velocity pressure coupling and a level-set method is used for free-surface capturing. The overset technique which is implemented in Suggar++ library is adapted for moving body problems. The realizable k-ε model with wall function is applied to model turbulent flows (Kim et al., 2017). Recently, generating oblique waves and solving six degree-of-freedom equations of motion have been implemented toWAVIS code for the present research. | - |
