摘　　要：针对浮泥层对船船干扰的影响问题,通过求解RANS方程对浮泥水域中追越船与被追越船间的水动力干扰问题进行数值模拟.对比分析了有无浮泥时追越船与被追越船所受力和力矩特点,讨论了在浮泥水域中不同水深吃水比、富裕水深及航速比变化对两船所受力和力矩的影响.结果表明:浮泥层会扩大船船干扰的范围;追越船所受力和力矩及被追越船所受力矩各极值随富裕水深的增大而减小;水深吃水比一定时,追越船所受力和力矩各极值随浮泥厚度的增大而增大;被追越船所受力和力矩各极值随航速比的增大而减小;船尾散波发散角度随船速的增大而减小.Aiming at the influence of floating mud layer on ship-to-ship interference,the hydrodynamic interference between overtaking ship and being chased ship in floating mud waters was numerically simulated by solving RANS equation.The characteristics of the forces and moments on the overtaking ship and the overtaken ship with or without floating mud were compared and analyzed,and the influences of the changes of different water depths,draft ratios,abundant water depths and speed ratios on the forces and moments on the two ships in the floating mud waters were discussed.The results show that the floating mud layer will expand the scope of ship-to-ship interference,and the extreme values of the force and moment on the overtaking ship and the moment on the overtaken ship will decrease with the increase of the rich water depth.When the depth-to-draft ratio is constant,the extreme values of the force and moment on the overtaking ship increase with the increase of the thickness of the floating mud.The extreme values of the force and moment on the overtaken ship decrease with the increase of the speed ratio,and the divergence angle of the stern wave decreases with the increase of the ship speed.
