摘要
The viscous hydrodynamic force and moment on ships moving obliquely in shallow water are 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—ωturbulence 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.
The viscous hydrodynamic force and moment on ships moving obliquely in shallow water are 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-ω 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.
