| Abstract: | The viscous hydrodynamic force and moment on ships moving obliquely in shallow water axe important for ship navigation safety. In the paper, the viscous flow field around a KVLCC2 model moving obliquely in shallow water is simulated and the hydrodynamic drag, lateral force and yaw moment acting on the hull are obtained by a general purpose computational fluid dynamics (CFD) package FLUENT with shear-stress transport (SST) k-w turbulence model. The numerical computation is performed at different drift angels and water depths. The numerical results are compared with experimental results, and a good agreement is demonstrated. |
