利用FUNWAVE 2.0模式模拟了不同初始高度和位置的立方体水面扰动引起的封闭矩形港和一组不同宽度和入口位置的部分开放矩形港内的振荡。立体水面扰动的高度和位置分别指其厚度和在港内的相对水平位置。所有港口内外的水深设定为恒定。本文的目的是研究不同的水面扰动高度和位置以及不同的港口入口宽度和位置对港内振荡的影响。结果表明，对于给定的港口和本文所研究的初始水面扰动高度范围，各特征频率的响应幅值均随初始水面扰动高度线性增加。水面扰动初始位置沿港后墙和港侧壁沿着的变化可分别显著改变各模态的横向和纵向振荡模式。港口入口宽度和位置的变化对各谐振模态响应幅值的影响均取决于其波节线和波腹线与港口入口的相对位置。
Oscillations within an enclosed rectangular harbor and a set of partially opened rectangular harbors with various widths and locations of entrance induced by cubic water surface disturbances with different initial heights and locations are simulated using FUNWAVE 2.0 model. The height and the location of the cubic water surface disturbance refer to its thickness and its relative horizontal position inside the harbor, respectively. The water depth inside and outside all harbors is set to be constant. The aim of this paper is to investigate how different heights and locations of the water surface disturbance and various widths and locations of harbor entrance affect the oscillations inside the harbor. Results show that for the given harbors and the range of the initial height of water surface disturbance studied in this paper, all the response amplitudes of various eigenfrequencies increase linearly with the initial height of water surface disturbance. The variations of the initial location of water surface disturbance along the backwall and sidewall of the harbor can significantly change the transverse and longitudinal oscillation patterns of various modes, respectively. The effects of the variations of the width and location of the harbor entrance on the response amplitudes of various resonant modes both depend on the relative positions of their node lines and antinode lines to the harbor entrance.
