| Abstract | A set of CFD simulations and physical experiments were performed on a 2D surfaced submarine section. The goal of the study was to determine the effects on roll motion of a closed versus free flooding casing. Several casing configurations were examined. It was found that the casing opening size had a significant impact on roll damping, and that under-casing obstructions had only a minor effect. It was also determined that the submarine's roll behaviour was sensitive to its vertical centre of gravity. These observations were confirmed by the physical model tests. The conclusion from this study was that a floodable casing would be required in future 3D seakeeping physical model tests in order to best reproduce full scale behaviour. |
