| Abstract: |
| A three-dimensional time-domain potential flow model is developed and applied to simulate the wave resonance in a gap between two side-by-side rectangular barges. A fourth-order predict-correct method is implemented to update free surface boundary conditions. The response of an up-wave barge is predicted by solving the motion equation with the Newmark-β method. Following the validation of the developed numerical model for wave radiation and diffraction around two side-by-side barges, the influence of up-wave barge motion on the gap surfaceresonance is investigated in two different locations of the up-wave barge relative to the back-wave barge at various frequencies. The results reveal that the freely floating up-wave barge significantly influences the resonance frequency and the resonance wave amplitude. Simultaneously, the up-wave barge located in the middle of the back-wave barge leads to a reduction in the resonance wave amplitude and motion response when compared with other configurations. |

| 三维时域势流模型开发并应用于模拟两个并靠驳船间的窄缝共振现象。自由水面的更新采用四阶预报校正方法。迎浪驳船的运动响应采用newmark-β法求解运动方程得到。首先通过研究两个并靠驳船的辐射和绕射问题验证了已开发数学模型，随后计算了不同入射波浪频率下迎浪驳船的运动对窄缝内共振波高的影响，其中迎浪驳船相对背浪驳船位置不同。结果表明自由漂浮的迎浪驳船影响了窄缝内流体的共振频率并显著影响了共振波高。同时，迎浪驳船位于背浪驳船正中央时共振波高最小。 |
