Résumé
Six-DoF Unsteady-Reynolds-Averaged-Navier-Stokes (URANS) CFD simulations are conducted using the body-force propeller based on the Hugh & Ordway model with Goldstein Optimum distribution to study and validate the maneuvering performance of KRISO container ship with the appended rudder in calm sea at Froude number Fn = 0.26. The 35? port-side turning circle, 10?/ 10? zig-zag starting to port, 20?/ 20? zig-zag starting to port, and 20?/ 20? zig-zag starting to starboard maneuverers suggested by the SIMMAN 2020 workshop are used for the validation study. Before the maneuvers are executed, the rudder is brought to the neutral position using a PID controller control such that the yaw angle is zero to mimic the suggested initial conditions. The two-phase incompressible simulations are solved using the STAR-CCM+ CFD software. The hull and rudder are meshed as separate overset grids to allow the 6DoF motion of the hull and the deflection of the rudder. The time histories of the predicted ship trajectory, motion, orientation, and velocities are illustrated and validated against the experiments, along with a comparison of maneuvering-specific parameters. The comparisons show that the use of the body-force propeller model is an efficient and effective method for ship maneuvering simulations
