Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The choice of the turbulence model is very important to calculate the hydrodynamic forces of yawed ship in ship computational fluid dynamics (CFD). Based on SST k-w turbulence model, the total resistance, transverse force, bow turning moment and distribution of total pressure of body surface in viscous flows are calculated during one container model navigating at different drift angles, such as 00, 30, 60, 90, and 120, respectively. Then hydrodynamic position derivatives acting on the ship maneuvering motions are also calculated by least square cure fitting. The results of numerical calculation are analyzed qualitatively, combined with some correlative references and previous correlative ship research, and then it is conclude that the numerical simulation results are acceptable. The research indicates that SST k-w model is reasonable and credible when it is applied to the calculations of hydrodynamic forces of ship drift motion, and the kind model and the research results may direct ship designers, owners and operators in the future.
