摘　　要：以标准船型(KCS集装箱船)为对象,采用RANS方法,结合切割体网格自动划分技术,对大型集装箱船舶在浅水水域航行时的流场进行了数值模拟,通过设置不同水深吃水比,分析集装箱船舶在不同水深下的阻力和流场变化规律.研究表明,大型集装箱在深水航行时,当水深吃水比H/T>3时,浅水效应不明显;当水深吃水比H/T<3时,浅水效应明显;随着水深的减小,船舶剩余阻力增加明显,船行波波态变化明显,影响范围增加.In order to analyze the influence of water depth on the ship resistance and flow field of large container ships sailing in shallow water,taking the standard KCS container ship as the object,the flow field of large container ships sailing in shallow water was numerically simulated by RANS method combined with the automatic mesh generation technology of cutting body.The ship resistance and flow field of ships in shallow water were analyzed by setting different water depth draft ratio.The variation of flow field provides a reference for the study of hydrodynamic characteristics of large container ships sailing in shallow water.It is found that when the depth to draft ratio is more than 3,the shallow water effect is almost not obvious,when the depth to draft ratio is less than 3,the shallow water effect is obvious with the decrease of water depth,the ship residual resistance increases obviously,the wave state changes obviously,and the influence range increases.
