The effects of a high-speed frigate model passing close to a moored container model alongside a closed quay are experimentally and numerically investigated with a focus on ship-generated waves, transient ship motions, and hydrodynamic forces acting on the moored ship. Scaled model experiments are conducted to investigate the hydrodynamic interactions between the passing ship-generated waves and the moored ship. A RANS-based CFD method is applied to solve the hydrodynamic problem including the effect of the free surface. The overset mesh technique is adopted to simulate the relative movements between the two vessels. The numerical method is compared with experimental results for the ship-generated waves and total resistance in open water, then validated for the passing ship problem in restricted water. Numerical simulations are carried out to study the effect of different parameters on the passing ship effects. Results show that water depth, passing speed, and separation distance are important parameters that influence the transient interaction. The shape of hydrodynamic interaction forces and moments on the moored ship at relatively high speeds is different from the well-known behaviour at slow speeds. In practice, the most effective measure to reduce the effects of passing ship is to control the speed of the passing ship.

高速过关船对系泊集装箱船影响的实验和CFD研究

通过实验和数值研究,研究了高速护卫舰模型靠近停泊的集装箱模型并靠近封闭码头的影响,重点是船舶产生的波浪,瞬态船舶运动和作用在停泊船舶上的流体动力。进行了比例模型实验,以研究经过的船舶产生的波浪与系泊船之间的水动力相互作用。应用基于RANS的CFD方法解决流体动力学问题,包括自由表面的影响。采用过冲网格技术来模拟两个容器之间的相对运动。将数值方法与实验结果进行了比较,比较了舰船在波浪中产生的波浪和总阻力,然后针对受限水域中的过船问题进行了验证。进行了数值模拟,以研究不同参数对过船效果的影响。结果表明,水深,通过速度和分离距离是影响瞬态相互作用的重要参数。相对较高的速度时,系泊船上的流体动力相互作用力和力矩的形状与低速时的众所周知的行为不同。实际上,减少过船影响的最有效措施是控制过船速度。相对较高的速度时,系泊船上的流体动力相互作用力和力矩的形状与低速时的众所周知的行为不同。实际上,减少过船影响的最有效措施是控制过船速度。相对较高的速度时,系泊船上的流体动力相互作用力和力矩的形状与低速时的众所周知的行为不同。实际上,减少过船影响的最有效措施是控制过船速度。
