Coupled fluid structure interaction to model three-dimensional
dynamic behaviour of ship in waves
Increase in computational power over the recent years has made it possible to investigate fluid-structure interaction problems using RANS/CFD and Finite Element software. However, the majority of these investigations are carried out using one-way coupling, thus omitting important fluid-structure interactions. A strong or two-way coupling between RANS/CFD and FEA is presented in this paper to model symmetric motion and response of flexible floating bodies in regular head waves. To illustrate this application, the RAOs of vertical displacements and wave-induced loads are calculated at various locations along a flexible three-dimensional barge (3-D) barge. The structure of the flexible barge is modelled as beam, in line with the flexible backbone model used in the experiments. The computational results are compared with experimental measurements and two-dimensional (2-D) linear hydroelastic predictions. A preliminary investigation for the static, still water, response of a flexible S-175 container ship model is also presented.

Abstract
Increase in computational power over the recent years has made it possible to investigate fluid-structure interaction problems using RANS/CFD and Finite Element software. However, the majority of these investigations are carried out using one-way coupling, thus omitting important fluid-structure interactions. A strong or two-way coupling between RANS/CFD and FEA is presented in this paper to model symmetric motion and response of flexible floating bodies in regular head waves. To illustrate this application, the RAOs of vertical displacements and wave-induced loads are calculated at various locations along a flexible three-dimensional barge (3-D) barge. The structure of the flexible barge is modelled as beam, in line with the flexible backbone model used in the experiments. The computational results are compared with experimental measurements and two-dimensional (2-D) linear hydroelastic predictions. A preliminary investigation for the static, still water, response of a flexible S-175 container ship model is also presented.
