摘　　要：为研究C11型集装箱船的大幅横摇阻尼,基于STAR-CCM+软件平台,使用重叠网格技术和流体体积函数(VOF)方法,通过求解纳维-斯托克斯方程,对该船零航速和有航速下自由衰减横摇运动进行数值模拟.数值模拟结果表明:湍流模型、运动方程约束自由度设置情况、初始横摇角释放时间等对横摇结果影响较大;使用k-epsilon湍流模型、放开6自由度、待流场稳定后释放船模所得的计算结果与试验值符合较好.In order to study the roll damping of ship in large amplitude motions, numerical simulation based on STAR-CCMff-software was carried out by solving Navier-Stokes equation and using the o- verset mesh and volume of fluid （VOF） methods. The free decay roll motion of the Cll ship with and without forward speed was simulated. Numerical simulation shows that the turbulence models, the constraint setting of the degree of freedom and the time moment when the initial roll angle is released influence the simulation results. Numerical results are in good agreement with the experimental data when the k-epsilon turbulence model, the six degrees of freedom is unrestrained and the initial roll an- gle released after the steady flow field achieves are adopted in the simulation.
