Sažetak
Ship collisions are marine accidents with potentially large impact on the safety of human lives, environment and ship structural damage. Large- and model-scale experiments have revealed that the sloshing of fluid in partially filled tanks influences the collision dynamics and lowers the energy available for structural deformations. This paper presents a numerical analysis of sloshing interaction in collision. The model is based on the arbitrary Eulerian-Langrangian (ALE) finite element method with multi-material option. Freesurface elevation and motions evaluated numerically are compared to those from the model-scale experiments. Comparison reveals that the free-surface elevation inside the partially filled tanks is well predicted with the numerical approach. The difference in the rigid body velocity indicates however that the amount of energy in the sloshing fluid is somewhat overestimated.
