摘要

在迎面波浪中，由于某些浮动结构的结构构造，可能会出现因冲顶而造成的水柱冲击，从而降低作业性。浮筒附近的波浪衰减可降低水柱冲击的风险。本文对各种板式固定自由表面防波堤的性能和衰减机制及其防止水柱冲击邻近结构的能力进行了数值研究。在自由表面存在的情况下，采用基于 Navier-Stokes 方程的数值方法进行了二维模拟。在两种不规则海况下，对防波堤模型进行了波浪传播、反射和能量耗散方面的评估，并评估了其减少水柱对相邻结构影响的能力。结果发现，60 度倾斜板可减少大量波浪能量，波浪传播和反射很小，承受的波浪载荷也很小，同时还能有效减少水柱的冲击。

Force and water jet impact reduction on adjacent structures by means of free surface breakwaters

In head waves, water jet impacts due to run up can occur as a result of the structural configuration of some floating structures, reducing workability. Wave attenuation near the floater may reduce the risk of water jet impacts. This paper presents a numerical study of the performance and attenuation mechanisms of various plate type fixed free surface breakwaters and their ability to prevent water jet impacts on adjacent structures. Simulations are performed in two dimensions with a numerical method based on the Navier–Stokes equations in the presence of a free surface. The breakwater models are evaluated in two irregular sea states in terms of wave transmission, reflection and energy dissipation and by their ability to reduce water jets impacts on adjacent structures. A 60 degree inclined plate is found to induce a large wave energy reduction, little wave transmission and reflection and to experience little wave loading while effectively reducing water jet impacts.
