| Abstract: | With the finite volume method(FVM), the mathematical model of flow field in bridge area is discretized and mathematically solved. Then, the changes of flow field affected by the construction of bridge were studied. According to different flow field, ship's trajectories in bridge area are simulated with ship manoeuvrability model, MMG model. By full-scale experiment with DGPS in bridge area, taking into consideration of ship's excursion model in real navigation environment, comparison of ship's trajectory between numerical result and full-scale experimental result was analyzed. The comparison shows the importance of hydrodynamic interference forces between ship and pier and bank suck effect. |
