船舶在浅水中倾斜运动时所受的粘性水动力和粘性力矩对船舶航行安全具有重要意义。本文采用通用计算流体力学程序FLUENT中的剪应力输运k-ω湍流模型，模拟了KVLCC2船型在浅水中倾斜运动时的粘性流场，得到了作用在船体上的水动力阻力、侧向力和横摆力矩。在不同漂移角度和水深下进行了数值计算。将数值计算结果与实验结果进行了比较，结果表明两者吻合较好。
The viscous hydrodynamic force and moment on ships moving obliquely in shallow water are important for ship navigation safety. In the paper, the viscous flow field around a KVLCC2 model moving obliquely in shallow water is simulated and the hydrodynamic drag, lateral force and yaw moment acting on the hull are obtained by a general purpose computational fluid dynamics (CFD) package FLUENT with shear-stress transport (SST)k-ωturbulence model. The numerical computation is performed at different drift angels and water depths. The numerical results are compared with experimental results, and a good agreement is demonstrated.
