초록
In this study, the dynamic behaviors of a two-dimensional section of a floating body in waves are predicted using a modified particle-based method with a turbulence model. To predict the motion of a floating body, the free roll decay problem is simulated using the passively moving-solid model and the results are validated by comparing with the experiments. For the motion analysis on a floating body in waves, several types of cargo condition assumed to be partially-filled with solid and liquid cargos, such as water and oil, are simulated both with and without damage. As a result, the case loaded with liquid cargo showed more stable motion compared to the case with solid cargo. In addition, in the case with oil are damaged, the oil leak from the damaged part as well as the appearance of the leaked oil spilling towards inland sea are confirmed with a time lapse.
