摘要

采用CFD模拟方法，对KCS集装箱船在浅水中进行之字形和回转机动进行了数值研究。研究了网格密度、超调离散化、螺旋桨模型、湍流模型和设置条件等影响数值预报精度的因素。在1/52.66比例尺、弗劳德数Fr = 0.095、水深吃水比h/T = 1.2条件下，对KCS船模左舷、右舷转圈机动和3种不同之字形机动的数值预测结果与Flanders Hydraulics （FH）的实验数据进行了比较。为了更好地评估数值预测的准确性，在非密闭和密闭两种情况下进行了模拟。

CFD simulation of turning circle and zigzag maneuver of KCS in shallow water

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.
