| Abstract: | Bow lifting body technology has been demonstrated---via computational fluid dynamics, scale-model tests, and full-scale at-sea trials---to provide reduced motions at zero and loiter speeds, which can improve the seakeeping of hull. In this paper, the free surface is captured by Volume of Fluid (VOF) method and the numerical results of lifting force, drag and wave patterns are presented for the lifting body at different angle, submergence and velocity with the free surface. The results in the paper will support the research of favorable interference between bow-lifting-body and hull in the future. |
