초록
The sloshing problem is a critical issue in the design of liquid cargo carriers, especially for partially filled tanks. The violent change in the free water level inside a tank caused by ship motions in rough sea conditions generates a large impact on the tank walls, which leads to structural damage to the cargo containment system in the cargo tank. Therefore, several studies have been conducted to find an appropriate method for reducing sloshing impact damage. In this study, the effect of baffles on sloshing impact loads was numerically investigated using the coupled Eulerian-Lagrangian technique, which is generally applied to fluid-structure interaction analysis by combining the advantages of the Eulerian and Lagrangian formations. Two-dimensional numerical simulations have been performed and compared with previous research results to investigate the effect of vertical and horizontal baffles at various positions and lengths.
