Research Abstract

Investigation of ship motions in waves would be one of the crucial issues in ship-hydrodynamics to achieve safety transportation of surface vessels in real sea state. Computational Fluid Dynamics(CFD) software has been developed in order to solve incompressible viscous flow around ships moving in waves. The validity of the code has been confirmed throughout comparisons between computational results and experimental/reference data of unsteady motions of 2D and 3D objects.
