Abstract
Based on the open-source code OpenFOAM, a hybrid method based on the fully nonlinear potential flow method (FNPT) and the viscous flow method, combined with the propulsion model of the propeller and rudder, is used to simulate the turning and zigzag maneuvering motion of a single-screw ship in stern and beam waves. The wave is generated by FNPT, and the 6DOF maneuvering motion in waves and the ship-wave interaction are simulated by the viscous flow method in the internal field. The force and moment of the propeller and rudder are obtained by the propulsion model to improve the computational efficiency. The KVLCC2 model is used as the object for numerical simulation, and the numerical method is validated by the self-propulsion tank test. The maneuvering motion of the ship at the designed speed in stern and beam waves is simulated, and the turning and heading performance of the ship in the stern and beam waves is studied and analyzed by changing the wavelength.
