Numerical Simulation of Ship Yaw Maneuvering in Deep and Shallow Water

In this paper, the results of hydrodynamic forces and moments for a ship are determined in conditions of pure yawing with a Froude number of 0.24 in deep(h/T=25) and shallow(h/T=2) water. All these simulations are completed by our hydrodynamic Unsteady Reynolds Averaged Navier-Stokes (URANS) solver naoe-FOAM-SJTU based on the open source package OpenFOAM. A new 6DOF module has been extended to the solver to accurately simulate the oblique towing tests. This paper also provides investigations for flow features, including wave patterns of free surface and vorticalstructure.The effects of shallow water have also been investigated.
