摘要

The KCS Container Ship executing zigzag and turning circle maneuvers in shallow water is studied numerically with CFD simulation. Different factors affecting the accuracy of the numerical prediction such as grid density, overset discretization, propeller model, turbulence modeling and setup condition have been carefully investigated. Numerical predictions for port side and starboard side turning circle maneuvers and 3 different zigzag maneuvers are compared with experimental data obtained by Flanders Hydraulics (FH) for the KCS ship model at scale 1/52.66 with Froude number Fr = 0.095 and water depth to draft ratio h/T = 1.2 in tank conditions. To better assess the accuracy of the numerical prediction, simulations have been performed both with a non-confined and confined configuration.
