基于SPH法波浪破碎数值模拟分析

Numerical simulation analysis of broken waves based on SPH technique

运用SPH方法通过对造波板推程、周期、斜坡角度等参数对随机波浪传播过程中形成的不同的破碎波进行数值模拟,分析流场中随机波浪的波速、作用在基床的波压等水力性能,并将之与实际情况进行对比分析,更加直观地展现了波浪破碎的过程,得到波浪参数对于破碎的影响规律。

Using SPH（Smooth Particle Hydrodynamics） method in this paper by factors such as wavemaker stroke,cycle,slope of the inclined plane and so on to control of coastal beach,simulating the wave form of three broken styles and analyzing of the wave properties such as velocity and pressure were carried out,as well as the comparing with the actual situation. It is concluded that SPH method have a great advantage on the processing of wave break and its influence causes.
