Numerical simulation of ship maneuvring by a hybrid method with propulsive factors in waves taken into account

Abstract

In this paper, based on the open-source code OpenFOAM, a hybrid method coupling the FNPT-based QALE-FEM and the viscous flow method is used to simulate the turn and zigzag maneuvers of the single-screw ship in waves. The external domain adopts the fully nonlinear potential flow theory to simulate the wave tank. The internal domain simulates the interaction between waves and ships by the viscous flow method. The 6DOF motion equations are combined with the propulsive factors in waves to simulate the ship maneuvering during the simulation. The KVLCC2 model is used for numerical simulation. The numerical method is validated by the comparison with the self-propelled maneuvering test. Then, the turning and zigzag maneuvers of the ship in different initial wave headings and wave parameters are simulated, and the influences of wave heading and wave parameters on ship maneuvering are discussed.
