摘要

摘要: 利用二维数值波浪水槽研究波浪在防波堤前的运动状态.模型选用Navier-Stokes方程作为基本方程,以有限元法对基本方程进行离散.以直立堤前完全立波和越浪条件的不完全立波、斜坡堤前的不完全立波等典型情况的模拟为基础,组合这些典型情况模拟削角堤前不完全立波运动,探讨其堤前波面、波节点及波腹点位置、波压力等特性变化.

Abstract: The partial standing wave hydraulic performance in front of breakwater is studied by a two-dimensional numerical wave flume.In this numerical model,Nav ier-Stokes equation is chosen as the basic equation and discretized by the finite elements method.Several typical cases,such as standing wave invertical breakwater,partial standing wave in front of vertical breakw ater when wave overtopped,and partial standing wave in front of sloping structure,are simulated firstly.Combining these typical situations,the partial standing wave in front of a chamfered breakwater is simulated.The wave profile,the position of wave nodes and anti-nodes and wave pressures of this reflected wave are studied with the simulation results.
