采用数值模拟和物理模型试验相结合的方法，研究了并列式双矩形驳船间的波浪诱导流体共振及其横摇运动。基于开源计算流体动力学（CFD）软件包OpenFOAM的二维数值波浪水槽，应用于数值模拟。通过数值计算和收敛性验证，研究了双横滚驳船间差距内的流体共振特性。双横摇驳船间差距内流体的共振频率比双固定驳船间的共振频率低。通常情况下，双驳船在相反的方向上滚动，并且它们的平衡位置相对于初始竖直方向相反地倾斜。为进一步研究该问题，进行了双驳相对倾斜固定布置的物理模型试验。实验结果表明，共振频率随倾斜角的增大而线性减小，结合数值计算结果，双驳平衡位置的偏移是影响共振频率的一个重要因素。此外，研究了差距宽度和入射波高对流体共振与横摇运动耦合的影响。
The wave-induced fluid resonance between twin side-by-side rectangular barges coupled with the roll motion of the twin barges is investigated by both numerical simulation and physical model test. A 2D numerical wave flume, based on an open source computational fluid dynamics (CFD) package OpenFOAM, is applied for the numerical simulation. After numerical validations and convergent verifications, the characteristics of the fluid resonance in the gap between the twin rolling side-by-side barges are examined. The resonant frequency of the oscillating fluid in the gap between the twin rolling barges decreases compared with that between the twin fixed barges. Generally, the twin barges roll in the opposite directions, and their equilibrium positions lean oppositely with respect to the initial vertical direction. A physical model test is carried out for a further investigation, in which the twin barges are set oppositely leaning and fixed. From the present experimental results, a linear decrease of the resonant frequency with the increasing leaning angle is found. Combined with the numerical results, the deflection of the equilibrium positions of the twin barges is a relevant factor for the resonant frequency. Besides, the effects of the gap width and incident wave height on the fluid resonance coupled with roll motion are examined.
