| 摘 要： | 港口的几何形状是影响港湾共振的重要因素。本文从理论上推导了正六边形封闭港湾内各共振参数的解析表达式,并采用Boussinesq模型模拟了正六边形及其扩展形状港湾内的水波共振现象,验证了提出的理论,并进一步研究了各共振模态的空间能量分布特征。结果表明,变正六边形的一边为曲线后,港内水波能量分布更加集中于有限的共振模态上,不利于改善其内水波共振。

| Abstract: | The geometric shape of the harbor is one of the most important factors that influences harbor resonances.This paper theoretically deduces the analytical expression of the resonance parameters in the closed regular hexagon.The Boussinesq model is used to simulate oscillations within a regular hexagon and its extensional shapes basins.The analysis is verified and energy distribution inside the basin is investigated.Furthermore,energy will concentrate on fewer modes when one side of the regular hexagon becomes a curve,which is against the mitigation of harbor resonance. |
