| Abstract: | In order to estimate the added mass and damping of a crane ship,the numerical simulation of the heave,sway and roll motion of the ship was performed based on CFD theory.The sliding faces and the mixed grid approach were used herein.A hydrostatic roll experiment of ship model was carried out.Comparing the experimental measurement with numerical results,the feasibility of CFD simulation used to predict the hydrodynamic coefficients of the crane ship is demonstrated. |
