A STUDY ON MANOEUVRING HYDRODYNAMIC FORCES ACTING ON 3-D SHIP HULLS WITH FREE SURFACE EFFECT IN RESTRICTED WATER

The 3-D Rankine Source Method is applied to the computation of hydrodynamic forces and wave patterns of ship hulls moving in restricted water. Parabolic curved panels are adopted to model the hull surface and a body fitted grid is chosen to divide the local free surface. The lifting effect is simulated by a vortex surface placed on the longitudinal central plane of the ship and vortex filaments trailing from the whole vortex surface. The emphasis of this paper is put on the study of free surface and canal bank effects on the hydrodynamic forces. The conclusions obtained may improve ships safety in restricted water.
