计及浅水及岸壁效应的KVLCC2船体斜航运动水动力数值计算
Numerical calculation of hydrodynamic forces on a KVLCC2 hull in the oblique motion with shallow water and bank effects

通过求解不可压缩流动RANS方程，确定浅水及岸壁效应对船舶水动力的影响. 选用RNG k-ε湍流模型，使用全六面体网格进行离散，数值模拟了KVLCC2船体在不同水深和航道宽度情况下作直航和斜航运动时的粘性流场，得到作用在船体上的水动力. 将计算结果与试验结果对比，验证了计算方法的有效性.
To determine the shallow water and bank effects on ship hydrodynamic forces，numerical simulation of the viscous flow around a KVLCC2 hull in straight forward motion and oblique motion at different water depths and channel widths are conducted. RANS equations are solved. RNG k-ε model is adopted and hexahedral grids are used. The hydrodynamic forces acting on the hull are obtained. The comparison between the numerical results and experimental results demonstrates the validity of the proposed calculation method
