Implementation of fluid-structure interaction (FSI) in marine design: Calculation review on hull structures Available to Purchase

The current work presents a partitioned tightly coupled fluid-structure interaction (FSI) simulation. Fluid-structure interaction is an important aspect, accurate prediction method for ship dynamics is a significant prerequisite for structural design and an essential consideration for strength evaluation. In a seaway, the ship structure flexes constantly. It is subjected to neither static nor quasi-static loads. As a result, a dynamic interaction between the hull reactions and the activities of the surrounding fluid, known as fluid-structure interaction, is always present. This study has several conclusions, including the FSI effect associated with the hydrodynamic recovery force may have the most significant impact on the structural dynamic response. The major influence of restoring forces affects both structural damages and absorbed energy. Because of the effect of hydrodynamic restoring forces, multiphysics simulations for typical passenger ship disaster scenarios showed that appropriate FSI modeling may be necessary for either collision or grounding. Then, the fluid motion was identified on the dynamic behavior of the struck plate of a fluid tank, subjected to wedge impacts.
