正五边形港湾内的水波共振

Oscillations within a regular pentagon-shaped harbor

基于浅水长波假定,给出了正五边形封闭港湾内水波共振的解析表达式;并采用Boussinesq模型对该表达式进行验证。结果表明,正五边形封闭港湾内主要体现为类似一维港湾的单一波向上的共振,而产生共振的主要原因是壁面之间形成的驻波。

Based on the linear shallow water approximation, this paper presents analytic solutions for oscillation within a closed regular pentagon-shaped harbor. The Boussinesq model was used to verify the equation. The results show that oscillations in the closed regular pentagon-shaped harbor are similar to those in a one-dimensional water flume, and the resonance is mainly due to the standing wave between different walls of the harbor.
