Numerical investigation on turning maneuverability of intelligent ship by taking the shallow water effect
In this paper,with the help of STAR-CCM±,the turning maneuverability of intelligent ship considering the shallow water effect is numerically investigated.Firstly,the hydrodynamic performance of the intelligent ship in the unboun-ded flow is numerically solved,and the accuracy of numerical method is validated with the experimental results.On that basis,by changing the vertical distance between the ship and the ground wall,the shallow effect on turning maneuverability of intelligent ship is studied.The simulation results show that both the lateral force coefficient and the rolling moment coeffi-cient present sharp increase with the decrease of the ground distance.Relevant conclusions gotten in this article can provide some guidance for the safe sailing of intelligent ship in shallow water domain.
