摘　　要：船型参数对船体水动力性能的影响至关重要,合适的船体型线能够有效改善船体各方面性能。本文以KCS船型为例,首先采用CFD方法建立三维数值水池,通过VOF方法捕捉自由液面,并将RANS方程作为控制方程,模拟船体在不同速度下的总阻力和纵摇、升沉幅值。然后与实验值进行对比,结果表明本文采用的方法能够准确计算KCS船型的水动力性能。最后,研究船体长度和船体宽度的变化对船体水动力性能的影响。结果表明,船长对船体的水动力性能影响较大,而船宽仅对船体纵摇角度有较大影响。The influence of ship's parameters on the hydrodynamic performance of the hull is very important.The appropriate hull lines can improve ship’s hydrodynamic performance effectively.Taking the KCS ship as an example,firstly,the CFD method is used to establish a three-dimensional numerical tank.The VOF method is used to capture the free surface,and the RANS equation is selected as the control equation to calculate the total resistance and trim and sinkage of the ship at different speeds.Then the CFD results are compared with the experimental values.The results show that the calculation method used in this paper can accurately calculate the hydrodynamic performance of KCS ship.Last,the effects of the change of ship length and width on the hydrodynamic performance of the hull are studied.The results show that the ship length has a great influence on the ship's hydrodynamic performance,while the ship width only has a great influence on the trim of the hull.
