使用基于开源CFD软件包OpenFOAM®的二维（2D）数值波浪水槽研究了两个并排配置的相同固定箱之间的狭窄间隙内的共振水运动。间隙共振是由具有不同波高的规则波激发的，从线性波到强非线性波。本文主要对窄间隙中的自由水面高程和作用在物体上的波浪力（包括水平波浪力、垂直波浪力和弯矩）进行了谐波分析。结果表明，入射波高对不同物理量的高次谐波分量的影响是不同的。讨论了入射波高对反射系数、透射系数和能量损失系数的影响。最后，针对间隙共振的响应时间和阻尼时间的定量估计，首次提出了两种不同的方法，并对间隙共振进行了验证。
The resonant water motion inside a narrow gap between two identical fixed boxes that are in side-by-side configuration is investigated using a two-dimensional (2D) numerical wave tank based on OpenFOAM®, an open source CFD package. Gap resonance is excited by regular waves with various wave heights, ranging from linear waves to strong nonlinear waves. This paper mainly focuses on the harmonic analyses of the free-surface elevation in the narrow gap and wave loads (including the horizontal wave forces, the vertical wave forces and the moments) on the bodies. It is found that the influences of the incident wave height on the higher-order harmonic components of different physical quantities are quite different. The effects of the incident wave height on the reflection, transmission and energy loss coefficients are also discussed. Finally, aiming at the quantitative estimation of the response time and the damping time of gap resonance, two different methods are proposed and verified for the first time on gap resonance.
