柔性透水防波堤在波浪作用下的水动力特性研究
首发时间:2024-04-03
摘要:随着港口工作要求的提高,防波堤的消波性能逐渐无法满足日益增长的生产工作的需求。为了提高防波堤的消波性能,本文对防波堤结构提出改进,采用理论推导的方法以固定刚板防波堤为起点,通过改变其结构,提出一种柔性透水防波堤,并推导出其水动力学系数。本文基于势流理论,运用流域分解法,对柔性透水防波堤通过数值计算研究了不同孔隙率对反射系数、透射系数、能量损失的影响,为防波堤设计提供参考。

Study on hydrodynamic characteristics of flexible permeable breakwater under wave action
Abstract:With the improvement of port work requirements, the wave absorbing performance of breakwater can not meet the increasing demand of production work. In order to improve the wave absorbing performance of the breakwater, the structure of the breakwater is improved. A flexible permeable breakwater is proposed by using the method of theoretical deduction to change its structure, and its hydrodynamic coefficient is derived. Based on potential flow theory and watershed decomposition method, this paper studies the influence of different porosity on reflection coefficient, transmission coefficient and energy loss of flexible permeable breakwater through numerical calculation, providing reference for breakwater design
